The Miniature PLGR Engine – M-Code (MPE-M) GPS Receiver from BAE Systems is capable of receiving existing operational GPS signals along with the newer M-Code signal. It delivers geolocation and precise positioning capabilities for space-constrained applications while providing increased security and anti-jam capabilities. The MPE-M is size-compatible with the MPE-S receiver while offering a new security architecture for enhanced integrity, exclusivity, and resiliency. It has an advanced, dual-frequency RF front end that enables continuous track of both L1 and L2 GPS satellite frequencies. Even when turned off, a precise, low-power time source runs continuously to allow rapid acquisition of GPS satellites when the receiver is turned on again.
At its core, the MPE-M contains the required Selective Availability Anti-Spoofing Module (SAASM) functionality while providing increased mission effectiveness and safety enabled through the operation with the M-Code signal. It uses an advanced correlator engine for accelerated Direct-Y and Direct-M code acquisitions and implements next-generation modernized security architecture. The receiver includes black key capabilities such as Over-The-Air-Rekeying (OTAR) when available from GPS satellites. It supports all-in-view navigation of up to 12 GPS satellites continuously and includes anti-jamming and anti-spoofing for GPS-degraded environments.
The MPE-M is backward compatible for current users of the MPE-S embedded GPS receiver. It is available in a module that measures 6.2 x 4.5 x 0.7 cm and requires a DC supply of 3.3 V.
