Thales Navigation introduced last Thursday more accurate and robust DG16 and DG14 OEM boards for integration in high-end avionics systems.

DG16/14 is an excellent replacement for the Thales G12, until now the standard for superior performance in high-accuracy aviation and aerospace applications.

Thales DG16/14 boards are low-cost, new-generation, sub-meter GPS+Beacon+SBAS receivers for OEM integration with avionic systems for applications such as air traffic management.

The DG16/14 boards incorporate signals from Satellite Based Augmentation Systems (SBAS), such as WAAS, EGNOS and MSAS, to provide sub-meter differential positioning.

The DG16 is a 16 channel receiver with 12 GPS L1 code and carrier channels, 2 SBAS channels and 2 300 Khz DGPS beacon channels.

The DG14 is a 14 channel receiver with 12 GPS L1 code and carrier channels and 2 SBAS channels. Bother receivers can have their SBAS channels configured as two additional GPS channels to offer a total of 14 GPS channels.

RAIM Aids Accuracy

New on both the DG16 and DG14 is Receiver Autonomous Integrated Monitoring (RAIM), an algorithm that looks at each satellite signal to detect consistent bias errors and then exclude the signal.

RAIM detects large and consistent bias errors to improve accuracy. In addition, RAIM isolates a wrong satellite and corrects position and velocity errors.

HDMA Boosts Performance in Difficult Environments

The High Dynamics and Missile Application (HDMA) is now available on the DG14 board. It combines superior tracking algorithms and innovative hardware modifications for reliable tracking.

HDMA sets a new standard for unsurpassed performance and reliability in high acceleration, speed and vibration applications, making the DG14 board the most rugged off-the-shelf GPS receiver available.

Improved Vibration Resistance

In addition to HDMA, Thales has made physical changes to the DG16/14 boards to improve their performance in high vibration applications.

The boards now meet the MIL-STD-810E vibration specification defined in Category 10 "Minimum Integrity Test- General" with the use of just four mounting holes, allowing for easy and seamless upgrades from G12 HDMA boards.

Replaces Industry Standard G12 Board

The DG16/14 boards offer an excellent upgrade for customers of the Thales G12, GPS receiver board. The DG16/14 boards provide improved vibration resistance compared to the G12 and all the DG16/14 newest features, including SBAS and the Kalman filter.
