Multi-Sensor RTK/PPP Module
Multi-Sensor Fusion on a single board
for RTK and PPP
Our Multi-Sensor RTK Modul (MSRTK) is a high-quality solution without integration effort, for all situations with demand for highly accurate position and orientation.
The ANavS® Sensor Fusion working inside of the MSRTK, provides highly precise position information using the full potential of all standard sensors, namely GNSS receivers, an industrial grade internal measurement unit (IMU), vehicle data (wheel odometry and steering angle) and barometer. Information from additional sensors like Camera and LiDAR is already used inside the Sensor Fusion as well to get a precise and reliable position and orientation – Always.
The MSRTK has all standard sensors already on board.
It comes with up to three mass market GNSS receivers for precise position and attitude determination, all using multi-frequency signals from GPS, GALILEO, GLONASS and BEIDOU. Furthermore, it supports the connection of additional sensors, and therefore an easy integration inside the ANavS® Sensor Fusion, via numerous interfaces out of the box.
The name of the MSRTK comes from a positioning approach focused purely on RTK.
This approach relies on differential position determination based on receiving RTK corrections from stationary GNSS-stations. Ongoing developments for all satellite constellations, but especially for Galileo, brought up a second positioning method to become an adequate option, at least.
This method is known as Precise-Point-Positioning (PPP). It does no longer rely on differential position determination, but on precise orbit- and clock-corrections as well as code- and phase-bias corrections for the major Global Navigation Satellite Systems (GNSS). These High Accuracy Corrections Service (HACS) signals are broadcasted by the satellites or terrestrial link and can be received without additional infrastructure.
The ANavS® Sensor Fusion is ready to use these signals to determine a position based on a multi-sensor PPP approach.
With the MSRTK both positioning approaches can be used with the same set of connected sensors. No additional hardware is required and changes are only part of the configuration, meaning that the MSRTK can serve as a single hardware platform for the Sensor Fusion no matter if the position is determined using RTK or PPP.
The MSRTK is designed for a fast prototyping and product integration (OEM-board) and can directly be used after connecting the GNSS antennas. You can choose between an industrial casing and a printed light one for all applications where weight is a key requirement.

Why should I use the ANavS® MSRTK?
- The patented ANavS® tightly coupled sensor fusion provides real-time 3D-position, 3D-attitude (heading, pitch, roll), 3D-velocity and 3D acceleration information with an update-rate of up to 140 Hz.
- Temporary GNSS outages (in narrow street canyons, below bridges, in garages or tunnels) or high multipath (e.g. below trees) are overcome by the integration of additional sensors (IMU, wheel odometry, camera, LiDAR or UWB-based Local Positioning Systems (LPS)/ Real-Time Locating Systems (RTLS). Thereby, precise position and attitude information is still provided in challenging environments.
- We can flexibly configure the ANavS Multi-Sensor RTK module according to your needs: You can choose between one, two and three integrated GNSS receivers. If you are interested only in an accurate position, then one integrated GNSS receiver is totally sufficient. If you also need an accurate heading, you should have two integrated GNSS receivers. If you need a full 3D attitude information (heading, pitch and roll), then you should choose the version with three integrated GNSS receivers. The use of 3 instead of 1 or 2 GNSS receivers also improves the positioning accuracy for mainly two reasons: First, a precise attitude information enables a much more accurate correction of the gravity and, thereby, improves the benefit of the inertial sensor within the sensor fusion. Second, the number of GNSS measurements increases with the number of GNSS receivers, and thereby, enables a more stringent selection of the best GNSS observations. This leads again to a higher positioning accuracy.
