Micro GPS Receiver Application Module (MicroGRAM)

The world's smallest, lightest, lowest powered SAASM-based embedded GPS receiver for soldier and micro-applications

Missions and lives depend on warfighters' ability to find their way in unfamiliar, unpredictable territory. Not only do they need to know where they are, but warfighters also need an awareness of the participants and movements within their mission. With MicroGRAM, your forces carry these critical capabilities and more.

No other SAASM-based, embedded GPS receiver is as small, light or power efficient as MicroGRAM. Add to that its secure, precise location and positioning capabilities and MicroGRAM is ideal for size-constrained military micro-applications. It assists your forces with tactical communications, field computing and unmanned aircraft operating in a GPS-denied or -challenged environment.
