Description
The Air Force Research Lab (AFRL) intends to award a sole source contract for a LabSat 4 Global Navigation Satellite System (GNSS) Radio Frequency Record and Replay System. The system must match the currently owned hardware used in the project and have specific requirements such as multiple recording channels, interface to an inertial sensor, and ability to produce a NMEA stream output. The system must be field portable, fit in a 1U space on a server rack, and have an internal data drive that is replaceable. The contract is to support follow-on development for a FY26 new start effort under exploratory research.
• The system must offer multiple recording channels to capture at minimum live sky GNSS satellite data for a location in the Continental United States (CONUS) and must interface to an inertial sensor including the STIM300 inertial measurement unit (IMU).
• The system must collect data from a GNSS source (live sky or similar) and from an inertial measurement unit (or similar) on a synchronized time scale.
• The ability to produce a NMEA stream output is required.
• The system must be field portable and fit in a 1U space on a server rack so it may be installed in a standard server rack in test vehicles.
• The system must hold an internal data drive that is replaceable to meet data rate requirements without dropping samples, which would render the data unusable.
