Receiver Requirements
• Shortest TTFF– Customers do not care about channels, correlators, Ephemeris (extended or
not) – they want a fix NOW
• Highest sensitivity– Fix under all conditions – no worries about an antenna
• Lowest Power consumption– We mainly address telematics applications – but even here for asset tracking
this is the second priority – certainly this is very often a combination with short TTFF
• Jamming recognition, mitigation, removal– Especially automotive telematics suppliers ask for that – it is already normal
in GSM products
• Galileo support– Not a big issue today, but especially in Europe, customers are asking

SiRFaware™Technology
GPS OFF• Saves power, but…• Requires a lot of start-up energy• Compromises performance
GPS ON• Uncompromised
performance, but…• Burns up battery power

SiRFawareTM - Basics
Q: What is SiRFawareTM good for? A: SiRFawareTM keeps the module in a state of readiness for rapid
navigation for long periods!
Q: When and how can I start using SiRFawareTM? A: SiRFawareTM mode can be entered after an initial position
calculation by software command!
Q: How is SiRFawareTM able to accomplish this? A: SiRFawareTM will try to maintain position, time, frequency, and
Ephemeris!
Q: Can I further improve SiRFawareTM? A: SiRFawareTM can even be combined with Extended Ephemeris
methods!

SiRFawareTM – Power PRELIMINARYPRELIMINARY
• Data Collection (re-load of Ephemeris)– Every 30 minutes for ~ 18s @ 40mA– Calc. average: 40mA x 18s / (30 x 60s) = 400µA– Targeted average: < 500µA– Results so far: ~ 300µA
• Capture / Update (time, frequency, ... maintenance)– Every minute for ~ 250ms @ 30mA (worst case)– Calc. average: 30mA x 250ms x 30 / (30 x 60s) = 125µA– Targeted average: < 500µA– Results so far: < 300µA

Implementation
• Vcc should be always ON!• Toggle ON_OFF from LOW to HIGH to wake up after power on….• Use software command to initiate and get back from SiRFawareTM
and other low power modes…• Necessary configuration for UART mode:

Summary / Feedback
• Keep in mind– We are an early adopter, so there might still be a change
in design between the samples and production modules– Many features will be enabled with new firmware updates– Documentation is not perfect yet and CSR will release its
documentation in March only - but we can start!
• Further information to follow shortly• Your feedback is appreciated
• Thanks!
