DESCRIPTION
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.

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.
