    2. Summary Description

    This section provides an overall description of common firmware that can be used in any Jupiter GNSS receiver module based on the CSR GSD5e B02 device. The initial version of common firmware is based on the 5.7.7-P1 production release from CSR.

    2.1. Configuration Details A list of characteristics and default settings common to all variants of 5.7.7-P1 firmware is provided below.

    GPS and GLONASS constellations are enabled and used for navigation. QZSS satellite ranging is also enabled by default.

    Time Mark pulse (1PPS) is output on GPIO5.

    The GNSS_ON signal is output on GPIO8.

    The serial port default protocol is NMEA at a rate of 9600bps. The supported NMEA version is 3.01. GGA, GSA, GSV, and RMC messages are output once per second, all other messages are disabled by default.

    One Socket Protocol (OSP) serial data protocol is also supported.

    Static navigation (position pinning) is disabled by default.

    The groundtrack smoothing filter is disabled by default.

    Velocity propagation (dead reckoning) is disabled by default.

    Automatic altitude hold (2D navigation) is enabled.

    Three-satellite (2D) acquisitions are enabled.

    The default elevation mask angle for using satellite measurements is five degrees.

    Maximum altitude is 24km.

    The use of Satellite-Based Augmentation System (SBAS) satellite ranging for navigation, and SBAS satellite corrections for differential operation, is supported. However, SBAS usage is disabled by default.

    Differential operation using RTCM corrections is not supported.

    SiRFInstantFixTM Client-Generated Extended Ephemeris (CGEE) is generated for three days of GPS EE data and one day of GLONASS EE data.

    SiRFInstantFix Server-Generated Extended Ephemeris (SGEE) is supported for up to 14-day GPS EE files and 14-day GLONASS EE files.

    Continuous-wave and narrow-band interference detection and mitigation is performed for GPS and GLONASS frequency bands.

    The device wake-up feature is enabled. The module wakes up from a commanded Hibernate state if the ON_OFF input signal remains high and there is data traffic on the Host serial port.

    2.2. Variant Configurations Additional default settings that are unique to each of the available 5.7.7-P1 firmware variants are listed below.

    Start-up power mode is Full Power, internal LNA set to fixed Low gain mode. Start-up power mode is SmartGNSS-I, internal LNA set to fixed Low gain mode. Start-up power mode is Full Power, internal LNA set to fixed High gain mode. Start-up power mode is SmartGNSS-I, internal LNA set to High gain mode.

    2.3. Version Strings The version string for each variant of the 5.7.7-P1 firmware release is of the form: 5xp__5.7.7-P1.GCC_ N96[S1]+5xpt_5.7.7-P1.KCC If S1 is present, the start-up power mode is SmartGNSS-I instead of full power. If LG is present the internal LNA is set to fixed Low gain; otherwise if HG is present it is fixed High gain. As an example, the version string for the SmartGNSS-I, low internal gain variant is 5xp__5.7.7-P1.GCC_ N96S1LG+5xpt_5.7.7-P1.KCC

    When polled for the firmware version in NMEA mode, the module returns two version strings in the $PSRF195 message. An example for the SmartGNSS-I, Low internal gain variant is shown below: $PSRF195,5xp__5.7.7-P1.GCC+5xpt_5.7.7-P1.KCC*0A $PSRF195,N96S1LG*2E

    2.4. Notes on 5.7.7-P1

    Although the GNSS_ON output signal (GPIO 8) is supported, under some circumstances it will be set high when the receiver module is in the Hibernate state or when it is in a low power state during Trickle Power operation. These are states in which GNSS_ON is normally set low. If this signal is used to enable an external LNA, the RF front end will draw higher current if this behavior occurs.

    The NMEA datum control input message ($PSRF106) is not supported.

    Differential GNSS operation for GLONASS from SBAS is not supported.

    3. Change Descriptions

    This section details the changes made in subsequent versions of common firmware released by Telit for modules based on the GSD5e B02 device.

    3.1. Delta Software from Version 5.7.7 to 5.7.8 Version 5.7.8 is a production firmware release based on Qualcomm firmware version 5.7.8-P1, and it supersedes firmware version 5.7.7. Changes from 5.7.7 to 5.7.8 are listed in the subsections below.

    3.1.1. New Features

    Dual UART serial operation is supported. Ports can be configured as one OSP and one NMEA, or as both NMEA. However, protocol switching while maintaining dual port operation is not supported. Contact a Telit Sales Representative regarding requests for firmware variants configured for dual-UART operation.

    Support was added for 10Hz navigation updates.

    3.1.2. NMEA Messages

    A new command for datum control ($PSRF106) was added. See Reference 3 for command details.

    3.1.3. OSP Messages

    A new command, MID 169, for datum control was added. Name Bytes Example Description MID 1 U A9 Message ID Datum 1 U B2 Datum identification code Flag 1 U 01 Enable DTM sentence when switching to

    NMEA protocol Reserved 1 U 00 The example data selects Tokyo Mean local datum and enables the DTM sentence output if switching to NMEA protocol. The permitted datum identification codes are the same as that for the NMEA $PSRF106 command (see previous section).

    3.1.4. Improvements

    Default UTC offset has been updated to 17 seconds.

    Improvement has been made in the time to obtain GLONASS ephemeris data from weak signals in certain scenarios, sometimes resulting in improvement in TTFF in those cases.

    Reported C/No values have been improved when SmartGNSS mode is enabled. The C/No spikes that were seen during transitions between Full Power and SmartGNSS operating modes have been reduced.

    Positioning performance in urban canyon scenarios has been improved for Full Power mode so that it is comparable to performance when SmartGNSS is enabled.

    Trickle Power navigational performance has been improved.

    Improvement has been made in multi-path mitigation involving higher elevation satellites.

    3.1.5. Corrections

    Corrected the behavior of the GNSS_ON signal (GPIO8) where it would sometimes remain high even though the module was in a low power state (see section 2.4).

    Corrected an issue that caused GAGAN satellites not to be tracked.

    Corrected an issue whereby DGPS corrections were getting corrupted when multiple SBAS constellations were used.

    Corrected an issue that could cause maintenance cycles in Micro Power Mode (MPM) to have extended TTFF and consequently increased power consumption.

    Corrected an issue with MPM that caused MEMS Wake-up configuration information to be lost after the module was awakened from the Hibernate state.

    Corrected an issue with Push-To-Fix (PTF) low power mode whereby the module occasionally did not output the OKToSend message indicating receiver initialization complete in Full Power mode (MID 18 with indicator value 2).

    Corrected an issue that could cause incorrect heading output.

    Corrected the malformed NMEA GLGSV message after a cold start when no GLONASS satellites are in the visible list.

    Reproduction forbidden without Telit Communications S.p.A. written authorization - All Rights reserved page 13 of 18 Mod. 0811 2014-10 Rev.2

    Corrected the value returned in the NMEA SGEE age response (SPSRF156,22).

    Corrected an issue whereby OSP messages MID 54, SID 3 (PowerUp) and MID 54, SID 4 (PowerDown) were not sent out when the module was operating in a low power mode.

    Corrected an issue whereby OSP MID 18, SID 1 (OkToSend) was being output twice during a software reset.

    Corrected the failure to NACK OSP input messages with invalid checksums or invalid message lengths.

    Corrected the absence of an ACK or NACK response to OSP message MID 222, SID 16 (Location Technology Constraints).

    3.1.6. New Variant Configurations

    For each of the variant configurations described in Paragraph 2.2, the PPS signal starts being output once the module achieves navigation with five SVs, and ceases being output when the module falls out of navigation. With version 5.7.8-P1 firmware, additional variants are available in which the default PPS behavior is changed so that it is output under less restrictive conditions. The PPS will start being output when the module achieves navigation with four SVs, and continues being output upon loss of navigation.

    3.1.7. Version Strings

    The complete version string returned in OSP MID 6 for each variant of the 5.7.8-P1 firmware release is of the form: 5xp__5.7.8-P1.GCC_5xpt_5.7.8-P1.KCCN96[S1][PPS]+ 5xpt_5.7.8-P1.KCC If S1 is present, the start-up power mode is SmartGNSS-I instead of full power. If LG is present the internal LNA is set to fixed Low gain; otherwise if HG is present it is fixed High gain. As an example, the version string for the SmartGNSS-I, low internal gain variant is 5xp__5.7.8-P1.GCC_ 5xpt_5.7.8-P1.KCCN96S1LG+5xpt_5.7.8-P1.KCC

    If PPS is present, the PPS signal is output is under less restrictive conditions. At start-up the PPS will start being output when the module navigates using four SVs rather than five SVs. And upon loss of navigation, the PPS will continue to be output.

    Reproduction forbidden without Telit Communications S.p.A. written authorization - All Rights reserved page 14 of 18 Mod. 0811 2014-10 Rev.2

    When polled in NMEA mode, the module returns two version strings in a pair of $PSRF195 messages. The first message is the same for all 5.7.8-P1 firmware variants, while the second message is unique to the variant. An example for the SmartGNSS-I, low internal gain variant is shown below: $PSRF195,5xp__5.7.8-P1.GCC+5xpt_5.7.8-P1.KCC*0A $PSRF195,N96S1LG*2E

    3.1.8. Notes on 5.7.8-P1

    Differential GNSS operation for GLONASS from SBAS is not supported.

    3.2. Delta Software from Version 5.7.8 to 5.7.10 Version 5.7.10 is a production firmware release based on Qualcomm firmware version 5.7.10-P2.1, and it supersedes firmware version 5.7.8. Changes from 5.7.8 to 5.7.10 are listed in the subsections below.

    3.2.1. New Features

    Incorporation of GLONASS satellite measurements has been added to differential GNSS operation using corrections obtained from SBAS satellites.

    Static motion detection using a MEMS accelerometer has been added. This feature is only applicable to modules with a MEMS I2C interface.

    Drone platforms using OSP protocol are now supported. Firmware that is configured for use in drone applications will output a new OSP message (MID67, SID2) which is described in Reference 6. Contact a Telit Sales Representative or Technical Support Services regarding requests for firmware variants that are configured for drone platforms. Note – In firmware configured for drone platforms, the navigation filter is tuned for best overall performance at 5Hz.

    GLONASS-only and Beidou-only operating modes are supported. These modes can be

    commanded in OSP protocol using MID222, SID16 as described in Reference 6. Caution – Although these modes are supported, they have not been optimized, and therefore their performance has not been characterized.

    3.2.2. Improvements

    Average power consumption in SmartGNSS-II continuous low power mode has been improved through more efficient maintenance of satellite data obtained from GNSS satellites.

    Tunnel Detection logic has been improved in order to lessen the impact of tunnels on Trickle Power and SmartGNSS low power modes.

    Weak signal data collection for GLONASS satellites has been added, reducing the C/No threshold for downloading ephemeris from 27 dB-Hz to 23 dB-Hz.

    Position accuracy while operating in Trickle Power mode has been improved.

    3.2.3. Enhancements

    The command to switch from OSP to NMEA (OSP MID 129) has been updated to support NMEA bit rates that are higher than 57600 bps. For higher rates, the baud field value represents the lower 16 bits of the desired baud:

    o 49664 (0xC200): 115200 bps o 33792 (0x8400): 230400 bps o 2048 (0x0800): 460800 bps o 4096 (0x1000): 921600 bps o 49152 (0xC000): 1228800 bps

    Support for navigation using the new Type K1 GLONASS SVs has been added.

    Dual UART serial operation has been enhance to allow protocol switching under certain

    conditions when both ports are active. Protocol can be switched between OSP and NMEA one port, provided that the other port is NMEA.

    Search and acquisition of Beidou satellites has been expanded from 14 PRNs to all 37 PRNs specified by the Beidou Interface Control Document.

    3.2.4. Corrections

    An issue has been corrected that caused the speed over ground to be incorrectly reported in the NMEA VTG message as 0.0 when the module is operating at the 10Hz navigation update rate.

    Two issues related to Trickle Power have been resolved: o The receiver failed to switch to Full Power when the ON_OFF signal was

    toggled during Trickle Power.

    o When commanded to one-second updates and high power reduction using MID 218, SID 8, the receiver intermittently dropped an update and momentarily failed to meet the one-second rate.

    A problem that could cause the MEMS wakeup feature in SiRFaware to fail has been corrected. When the EIT signal was asserted due to motion, the signal would not wake up the module when the problem occurred.

    3.2.5. New Variant Configurations

    With version 5.7.10-P2.1 firmware, additional variants are available in which the default power mode can be set to SmartGNSS-II.

    3.2.6. Version Strings

    The complete version string returned in OSP MID 6 for each variant of the 5.7.10 firmware release is of the form: 5xp__5.7.10-P2.1.GCC_[S1|S2][PPS][HD]+ 5xpt_5.7.10-P2.1.KCC

    When N96 is present the serial port defaults to NMEA protocol at 9600 baud; otherwise when B115 is present the serial port defaults to OSP (binary) protocol at 115200 baud.

    If S1 is present, the start-up power mode is SmartGNSS-I instead of full power. Similarly, if S2 is present, the start-up power mode is SmartGNSS-II instead of full power.

    When LG is present the internal LNA is set to fixed Low gain; otherwise when HG is present it is set to fixed High gain.

    If PPS is present, the PPS signal is output is under less restrictive conditions. At start-up the PPS will start being output when the module navigates using four SVs rather than five SVs. And upon loss of navigation, the PPS will continue to be output.

    If HD (High Dynamics) is present, the firmware is configured for use in Drone applications.

    As an example, the MID 6 version string for the SmartGNSS-I, low internal gain variant that defaults to NMEA at 9600 baud is 5xp__5.7.10-P2.1.GCC_N96S1LG+5xpt_5.7.10-P2.1.KCC When polled in NMEA mode, the module returns two version strings in a pair of $PSRF195 messages. The first message is the same for all 5.7.10-P2.1 firmware variants, while the second message is unique to the variant. The output for the example above is: $PSRF195,5xp__5.7.10-P2.1.GCC+5xpt_5.7.10-P2.1.KCC*0A $PSRF195,N96S1LG*2E

    4. Notes

    EGNOS and GAGAN SBAS range measurements are not supported.

    SBAS ranging and differential operation require SBAS signals to have C/No values of at least 37dB-Hz when the module is in Full Power mode. When the module is in SmartGNSS-I power mode, SBAS signals must be even stronger in order for SBAS to be operational.
