NovAtel - FlexPak-S GPS RTK SAASM receiver

FlexPak-S GPS RTK SAASM receiver

DEFENSE AND CIVIL—COMBINING THE BEST OF BOTH WORLDS

System integrators have come to rely on the centimetre-level position accuracy available in Real Time Kinematic (RTK) commercial GPS receivers. Authorized defense customers need access to the Precise Positioning Service (PPS). The FlexPak-S contains the OEM625S™ card with commercial dual-frequency NovAtel receiver and an L-3 XFACTOR Selective Availability Anti Spoofing Module (SAASM).

When keyed, the FlexPak-S provides an RTK PPS solution by taking the raw measurements from an L-3 XFACTOR SAASM and applying them to NovAtel’s industry leading RTK algorithm. In the Standard Positioning Service (SPS) fallback mode, the FlexPak-S continues to provide centimetre-level accuracy by utilizing NovAtel’s dual frequency civil GNSS positioning engine.

OPTIONAL GPS+GLONASS TRACKING FOR GREATER PERFORMANCE

The SPS fallback mode of the FlexPak-S is configurable for GPS or GPS+GLONASS. Adding GLONASS tracking increases available position in obstructed sky conditions, making it ideal for unmanned ground vehicle applications.

RELIABLE AND RUGGED IN A COMPACT SIZE

Reliability is safeguarded as a result of the rugged and water resistant IP67 FlexPak-S housing combined with its wide operating temperature range. The FlexPak-S is a compact, lightweight enclosure that fits into most applications where small size is critical.

EASY SYSTEM INTEGRATION AND INSTALLATION

NovAtel has assured faster time to market by reducing integration time with standardized software and hardware connections. FlexPak-S provides numerous interfaces including multiple RS-232/RS-422 serial ports. NovAtel’s comprehensive set of software commands facilitates simple integration. SAASM security functions are provided over a dedicated interface, while the SAASM RTK position is provided through NovAtel’s software command protocol. FlexPak-S uses the same form factor as the popular FlexPak6™ design.
