Dependable reference and test systems for autonomous driving
In developing autonomous vehicle technologies, it is essential to have a reference model to verify driving performance. Self-driving vehicles will have to drive in a variety of environments on public roads, requiring a flexible reference and test system that can be deployed virtually anywhere.
Reflected satellite signals from structures, bridges and tunnels all result in significant jumps in position estimates. Pure GNSS systems are therefore not very dependable on the public roads.

NTRIP-DGNSS-Box 5
DGNSS-Korrekturdaten für hochpräzise Positionierung von einem RTK-Netzwerk-Provider oder von der GPS-Basistation
DGNSS Correction Data for High-Precision Positioning from RTK Network Provider or GPS Base Station
With the NTRIP-DGNSS-Box 5, an ADMA equipped with RTK capabilities can obtain positional correction data through the Network RTK (like SAPOS and ASCOS, SmartNet, …), without the need for a nearby Base Station. By receiving correction messages through the RTK network, this solution provides significant benefits when conducting tests over long distances, varying elevations, or areas with topographical obstacles that may obstruct communication with the Base Station.

Scope of delivery
Option RTK2: High-precision position measurement using correction data
RTK stands for Real-Time Kinematic and is a technique based on carrier-based distance measurement that can RTK stands for Real-Time Kinematic and is a technique based on carrier-based distance measurement that can determine positions with high precision.
The method is much more accurate than code-based location. The basic concept is to eliminate the various error sources of raw GNSS positioning by using a local base station whose exact position is known. For this purpose, correction data of a virtual base station of different correction data services can be requested, or a local base station with its own GNSS receiver is used.
Product-Page Option Multi-GNSS: Use of multiple satellite systems such as GPS, GLONASS, Galileo, Beidou
Today’s GNSS-Receivers have the option of accessing multiple satellite systems such as GPS, GLONASS, Galileo and Beidou.
By using these systems in addition to GPS the Receiver is able to track more Satellites which results in the following advantages:
Reduced signal acquisition time.
Improved position and timing accuracy.
Reduction of problems caused by obstacles such as buildings and leaves
Improved spatial distribution of visible satellites, resulting in improved position accuracy.
Moving Base Add-On: Relative distance calculation via post processing
Distance calculations in post processing between two or more vehicles with a relative position accuracy of +/-2cm
No need for online or offline RTK correction data.
The accuracy is achieved by combining the pseudo range-, carrier phase- and doppler- measurements of the Hunter and Target-ADMA. Post processing requires an ADMA-Raw-Data log only.
One more benefit of post-processing is that it eliminates the need for a radio link between the participants. This reduces setup efforts, and saves time. On top of that, the system eliminates data loss due to disconnections.
Mounting accessories
For all ADMA systems, various accessories are available for installation in the test vehicle

Add-On DELTA 1:5 : Relative data calculation via WiFi in real-time for multi-vehicle operation
The ”DELTA” Add-On enables the direct output of relative data between two vehicles, for example distance, velocity and angle. Other than a WiFi connection between the two ADMAs, no additional hardware is required.
Data is provided in real time with minimum latency. This option is widely used for ADAS tests, especially AEB, FCW and ACC. Our customers rely on the ADMA option both when establishing a precise distance reference and for distance control of steering robots.
DELTA option is available for all ADMA models
Option DGNSS Correction Data: Correction data reception via Ethernet
Ideal on public roads
The option provides the capability to receive DGNSS correction data forwarded from a second ADMA
via WiFi / Ethernet.
This is the preferred option for multi-vehicle applications, e.g. LSS, ACC-, AEB- und FCW testing.
This option is used in place of radio modems, increasing the availability of DGNSS correction data, especially on public roads.
