Add-On gPTP: Time synchronization

The generalized Precision Time Protocol (gPTP) spezifed as IEEE802.1AS is an advancement of the Precision Time Protocol (PTP) spezifed as IEEE 1588 and is used for precise synchronization of timestamps in Time Sensitive Networks (TSN). It enables accurate time coordination between different devices in a network with exceptionally high precision in the microsecond range. This precision is crucial for applications that require an exact time reference, such as those found in vehicle development for synchronized data capture and analysis.

The Add-On gPTP encompasses the functionalities, 2-Step and P2P. Moreover, the ADMA can operate as a gPTP Master within the gPTP network, allowing them to take a central role in maintaining synchronization. By integrating these advanced synchronization features, customers can achieve enhanced performance and reliability in their applications.

Add-On Smoothing: Define maximum step size for GNSS signal

The new feature allows users to set a maximum step size for GNSS control. This means that if the GNSS data jumps, for example due to poor GNSS conditions, the INS data in the selected POI will be approximated to the GNSS data by the maximum step size selected. Smoothing is available for INS Position, INS Velocity and Side Slip Angle in each POI and in the Robot Data output.
In addition, if the difference between the smoothing result and the GNSS data lasts longer than expected due to a very large jump, the measurement data will be reset to the unaffected values after a user-defined amount of time. Overall, this feature provides greater control and accuracy in the handling of GNSS and INS data.

Note: Only available in combination with RTK2 activation and dual antenna capable GNSS receiver

Option Full-INS: License for the full range of ADMA functions

For the full range of functions with all output values as with an ADMA inertial system.
With the help of the Full-INS license option you can upgrade your ADMA-Speed, which is dedicated for brake distance measurements, to full ADMA functionality. This unlocks the ADMANet data output and makes it possible to use further options such as Addon-DELTA or Addon-Filter.

Option Internal Memory

The option “Internal Memory” provides a solution for local storage of measurement data and configuration files on the ADMA. This makes it possible to dispense with a DAQ (Data Acquisition) device in certain situations. This has the advantage of significantly reducing the effort, time and complexity of the setup, since no further configuration steps are required for data recording and fewer hardware components are needed.

Raw measurement data is stored in internal memory in binary format. This raw data format is seamlessly integrated into the entire GeneSys toolchain, which allows the data to be conveniently analyzed, compared or further processed in the ADMA Data Analyzer after the measurement. Functions such as offline delta calculation using the Moving Base software or optimization using the Post-Processing Software ADMA-PP are available for this purpose.

Another significant improvement is the simpler and more consistent management of configurations. Different configurations for different applications and scenarios can be stored locally in the internal memory and recalled when needed. This facilitates handling and ensures a consistent way of working when configuring the ADMA.

Option Multi-CAN: Data output via several CAN channels simultaneously

Allows to split the CAN data stream to up to 5 CAN interfaces to provide more measurement data at higher data output rate.

Note: Separate CAN-2-5 cable is required
Not available for ADMA-SPEED and ADMA-Slim

Option Multi-GNSS: Use of multiple satellite systems such as GPS, GLONASS, Galileo, Beidou

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 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.

Option Vehicle Model

The 2D vehicle model is an important tool for describing the motion of a vehicle in an XY plane. It is used internally to predict the behavior of the vehicle under different conditions and thus to support the IMU (Inertial Measurement Unit). In situations where GNSS failures are likely, e.g. city driving or in tunnels, it is advisable to use external speed sensors to support the inertial data. If this is not possible, an adaptive vehicle model can be activated that continuously estimates model parameters during good reception conditions without affecting the inertial data. 

In case of GNSS outage, the estimated parameters of the adaptive vehicle model can be used to reduce the lateral drift of velocity and position and improve the quality of yaw and slip angle. However, it is important to note that the use of the 2D vehicle model is only beneficial for passenger cars; in fact, this feature may be detrimental for other vehicles. Therefore, it is important to carefully consider and evaluate the application of the model to achieve the best results.
