The SATPAK-VME-FORCE22 is a 6U form factor carrier board that is specifically tailored to accommodate the Trimble FORCE22 GPS receiver module.  The FORCE 22 is a military Precise Position Service (PPS) GPS receiver that provides 12 channel tracking, GRAM compliance, L1/L2, DS-102/DS-101 key loading, SAASM, 1PPS/10PPS/UTC/Time Mark, Have Quick interface, optional SINCGARS interface, PVT output, navigation capability, ICD-GPS-153 interface, Differential GPS interface, NMEA interface, Trimble Diagnostic interface, dual antenna input, external timing input, and 3 serial communication channels.The SATPAK-VME operates from single +5 VDC power.  The GPS receiver +5 volt power is fused using a resettable fuse that is thermally activated. Once the fault condition has been removed, the fuse will automatically reset after cooling.  Backup power for the FORCE22 is provided by an onboard rechargeable lithium battery.  The FORCE 22 utilizes three (3) independent serial interfaces.  The RS-232 and RS-422 signal levels for the three FORCE22 serial interfaces are converted to CMOS and then transmitted and received over the VME bus using an industry standard PC16554 quad universal asynchronous receiver transmitter (QUART). The QUART is initialized and accessed via a VME A24:D08(O) data transfers. The fourth unused port of the QUART can be dedicated to any user-defined function. Four interrupt sources can be programmed for interrupt level and priority via an interrupt control register for each source.  A separate interrupt vector register allows programmable 8-bit vectors.  Push-on jumpers allow selection of the SATPAK-VME base address.  The SATPAK-VME supports address modifiers 39, 3D, 29 and 2D as per the VME-Bus specification.   All of the critical FORCE22 signals are routed to the user-defined VME P2 connector pins for secondary access via the VME backplane.
