A UNIQUE GPS / IMU BASED NAVIGATION SYSTEM

The relative navigation information computed by Geo-RelNAV includes relative position, relative velocity (closure rate), and relative orientation. The Geo-RelNAV system works by transmitting data, through a data link, from the follower units to the leader unit where it is used in the relative computations. Geo-RelNAV provides a variety of ways to connect to a data link including via RS-232 and Ethernet and does not specify a data link type (i.e., TDMA) or operating frequency.

Applications

  • Probe & Drogue

  • Boom and Receptacle

  • Shipboard Landing

Benefits

Minimized sensor size and weight to meet payload restrictions

  • Available with different grades of IMU’s to support a wide range of application requirements

  • Aerial refueling applications: Probe- Drogue and Boom system

  • On-Board data logging of all sensors raw and navigation solution data.

  • The relative navigation can be provided between one leader and multiple followers

  • The system can be upgraded to vision-aided navigation for GPS-denied environments

  • Beside relative data, the system can also provide absolute PNT solutions of leader and multiple followers

  • Real time navigation and visualization tool for monitoring absolute and relative PNT data on leader and follower units

  • Additional aiding sensors, such as barometers, Altitude Heading and Refence Systems (AHRS), odometers, etc., can be integrated

  • Includes GPS antenna and cables

    • Anti-Jam Antennas are optional

  • Additional aiding sensors, such as barometers, Altitude Heading and Refence Systems (AHRS), odometers, etc., can also be integrated

  • VYO Real-Time Navigation Visualization Tool as convenient interface to visualize time, position, attitude and related information (TSPI) streamed data
