KVH Inertial Aboard UAVs via Geodetics, NovAtel

KVH Industries, Inc., has entered into a strategic partnership with Geodetics,
Inc., to provide high-performance positioning and navigation products
for commercial applications requiring high levels of precision, from unmanned
platforms to terrestrial navigation.
Geodetics is integrating the KVH1750 inertial measurement unit (IMU) into two
solutions: Geo-iNAV Advanced, a GPSaided inertial navigation system; and
Geo-RelNAV, a high-accuracy relative navigation, positioning, and orientation
system.
Also, NovAtel, Inc., has added the-KVH1750 as an IMU option in its SPAN
GNSS/INS line of positioning products.
The IMU-KVH1750 is a highperformance commercial off-the-shelf
(COTS) sensor that offers bias stability and repeatability, KVH said. The GeoiNAV
Advanced system is available for commercial applications such as
manned and unmanned aircraft and control, security platforms on land, air
and sea, surface or subsea unmanned vehicles, mobile mapping systems,
and photogrammetry and terrestrial navigation.
The KVH 1750 IMU incorporates KVH’s DSP-1750 fiber-optic gyro with very lownoise
MEMS accelerometers, providing six-degrees-of-freedom angular rate and
acceleration data.
For collision avoidance and vehicle-tovehicle navigation and communication
(V2V), the Geodetics Geo-RelNAV system offers a real-time relative positioning and
orientation solution that uses single- or dual-frequency GPS receivers and the
KVH 1750 IMU. The Geo-RelNAV provides precise relative position and orientation
between moving platforms such as manned or unmanned air, marine, and
ground vehicles. Relative position data is used for autonomous aerial refueling,
autonomous landing, and collision avoidance.
For NovAtel, the IMU-KVH1750 integrates with its OEM6 series of
receivers to provide a tightly coupled 3D navigation solution, the company
said. Offering customers continuous position, velocity and attitude (roll, pitchand azimuth)
measurements, a SPAN system is stable and available even
through periods when satellite signals are blocked or unavailable; it is designed
for mobile and airborne mapping applications as well as hydrographic survey
