DELTAS-3S Multi-Purpose GNSS Receiver


Manufacturer: | Categories: ,

The DELTAS-3S GNSS receiver from JAVAD GNSS is an 874-channel receiver with advanced interference mitigation. The receiver tracks all GNSS constellations with patented anti-jamming, anti-spoofing, and multipath reduction technologies.



The DELTAS-3S GNSS receiver from JAVAD GNSS is designed for multiple GNSS applications where reliable correction data, timing, and event markers are required. Based on the TRIUMPH-3 ASIC, this receiver tracks all GNSS constellations with patented anti-jamming, anti-spoofing and multipath reduction technologies to excel with reliability and signal quality.

A simple web user interface sets up a continuously operating reference station (CORS) or portable base station, with integrated NTRIP caster and cerver functions to transmit RTCM corrections via TCP or NTRIP.
