MicroGram GPS Module Image

The Micro GPS Receiver Application Module (MicroGRAM) from BAE Systems delivers geolocation and precise positioning capabilities for military applications such as tactical communications, field computers, and unmanned aircraft. It has a Selective Availability Anti-Spoofing Module (SAASM) at its core, which encapsulates all classified data and signal processing into one tamper-proof module to provide better security. The module is capable of 12-channel continuous satellite tracking and supports L1 and L2 dual-frequency GPS signal reception. It has a time accuracy of 100 ns and a velocity accuracy of 0.04 m/sec steady rate.

The MicroGRAM has two low-power, full-duplex serial data ports with the MPE-S heritage of ICD-GPS-153C. It has an optimized, lightweight, low-power design that uses CMOS logic for efficient message protocol compatible with MPE-S. There is 1 pulse per second input and output timing pulses available for the host application to synchronize time. Even when turned OFF, a precision time source runs continuously when auxiliary power is supplied to allow rapid acquisition of the GPS satellites when the MicroGRAM is turned ON. It requires a DC supply of 3.3 V and consumes less than 0.5 W of power during operation. The MicroGRAM is available in a module that measures 25.40 x 31.75 x 7.00 mm and has an operating temperature range from -40° to +85°C.
