Navsight Solution – Hardware Manual NAVSIGHTHM.1.3

2. Solution overview

Navsight is a comprehensive inertial navigation solution,
specifically designed for the survey markets. Leveraging
on existing SBG Systems inertial sensors, advanced
algorithms and high performance GNSS technology, it
also adds an incredibly easy to use setup.
Navsight solution is composed of various components
that can be adjusted or configured according to your
specific application needs:

The IMU is the main sensing element and the most important performance driving factor. In case of good
GNSS conditions and shallow water or entry level land/air survey, the Ekinox IMU can be selected. In case of
more challenging conditions, such as difficult GNSS environments, or high altitude / high depth survey, the
Apogee grade is the sensor of choice to maintain the best accuracy. In case of airborne survey with single
antenna setup, or more generally, for ultimate accuracy, the Horizon IMU should be selected. All IMUs are
delivered in a rugged IP-68 package, and Ekinox / Apogee IMUs have optional salt water proof titanium
enclosures.
The other main component is the processing unit. Available in a rugged IP-67 form factor or easy to
integrate rack enclosure, it embeds all the navigation algorithms processing, a dual antenna, triple
frequency GNSS receiver (optional), capable of PPP and centimetre precision using RTK, and all inputs and
outputs interfaces. In addition to the standard Inertial Navigation System outputs (precise position, velocity
and attitude), the marine variant of Navsight Processing unit also deliver precise Heave and delayed heave.
For some cost sensitive applications, it is also possible to select a simple MRU setup, with only Roll, Pitch,
Yaw and Heave outputs.
For easier installation, the Navsight Processing unit and IMU can be installed at different locations: IMU
close to the location we want to track (eg. Multibeam sonar), and processing unit, close to user. SBG
Systems tested successfully installations with more than 50m distance between processing unit and IMU.
The Navsight processing unit can be connected to a wide range of aiding sensors such as GNSS, DVL,
Odometer.
To achieve the best performance in every project, specific error models have been implemented to meet
applications requirements and to adapt the Ekinox 2 to your vehicle. Sensor configuration is made easy
through the modern embedded web interface.
Finally, the 8 Go embedded data-logger enables seamless post processing work-flow with Qinertia software.
This makes Navsight solution suitable for the most demanding applications.
Navsight solution is fully compatible with integrated Ekinox and Apogee series in terms of protocols,
firmware and features.
