GPS Modem GR87

Global Positioning System (GPS) satellites broadcast

signals from space that GPS receivers, use to provide three-

dimensional location (latitude, longitude, and altitude) plus

precise time. GPS receivers provides reliable positioning,

navigation, and timing services to worldwide users on a

continuous basis in all weather, day and night, anywhere on

or near the Earth.

Features

On chip 1Mb SRAM.

Low power consumption.

Multi path mitigation hardware.

Reacquisition time 0.1 seconds.

Applications

Military.

Aviation.

Agriculture.

Working

GPS GR87 is a highly integrated smart GPS module with a ceramic

GPS patch antenna. The antenna is connected to the module via an LNA. The

module is with 51 channel acquisition engine and 14 channel track engine, which

be capable of receiving signals from up to 65 GPS satellites and

transferring them into the precise position and timing information that can be

read over either UART port or RS232 serial port. Small size and high-end GPS

functionality are at low power consumption, Both of the LVTTL-level and

RS232 signal interface are provided on the interface connector, supply

voltage of 3.6V~6.0V is supported. The smart GPS antenna module is

available as an off-the-shelf component, 100% tested. The smart GPS antenna

module can be offered for OEM applications with the versatile adaptation in form

and connection. Additionally, the antenna can be tuned to the final systems’

circumstances.
