DELTA-DM Multi-Purpose GNSS Receiver


The DELTA-DM GNSS receiver from JAVAD GNSS is a two-antenna system with 864 channels for multi-frequency tracking of GPS, Galileo, GLONASS, QZSS, and BeiDou. It offers robust and reliable positioning for high-precision navigation systems.



The DELTA-DM GNSS receiver from JAVAD GNSS is a satellite-based two-antenna system in a compact, durable, and watertight enclosure. This system is based on their TRIUMPH technology implemented in the TRIUMPH-2 chip.

The DELTA-DM receiver offers 864 channels of multi-frequency GPS, Galileo, GLONASS, QZSS, and BeiDou. The dual-frequency code and carrier phase data from two antennas are processed to determine the heading angle and the RTK positions of the two antennas up to 50 times per second.

The Delta-DM is a robust and reliable receiver for high-precision navigation systems used in various applications, such as machine and traffic control, precision agriculture, etc.


  • 864 channels
