Theta TR-3S Duo INS GNSS-Aided Inertial Navigation System

Written by EAD Admin on 21st September 2026. Posted in GNSS Antennas.

The Theta TR-3S DUO INS is a small, advanced OEM GNSS-aided Inertial Navigation System that combines two complementary technologies: GNSS and INS. The footprint is suitable for any application requiring precise, uninterrupted navigation and attitude within a compact size. Patented anti-spoofing and jamming detection enhances resilience, complemented by a comprehensive suite of interfaces for various applications. Accelerometers and gyroscopes are fully calibrated, temperature compensated, and mathematically aligned to an orthogonal coordinate
system.

For uncrewed marine vessels, the Theta from Javad may be an interesting solution. Combining GNSS positioning with inertial navigation provides reliable positioning, heading, and attitude information, which is often critical for autonomous and remotely operated marine applications.

Depending on the project’s specific requirements, THETA TR-3S Duo can be configured as either a single-antenna or dual-antenna system. The choice generally depends on the required heading accuracy, vessel dynamics, and overall system architecture.

L1 L2 L5 Antennas from EAD offer enhanced precision

Written by EAD Admin on 23rd October 2019. Posted in News.

Two L1 L2 L5 antennas introduced recently by EAD enable enhanced precision and accuracy in global GNSS tracking and timing applications.

The MP-RTK is a global GNSS magnetic mount puck antenna which is robust and low profile with an active antenna element. Ideal for mobile non-permanent tracking and positioning installations where permanent mount antennas are undesirable, the MP-RTK antenna is compact, durable and waterproof. It is fed by a 3M cable as standard which exits from the side of the unit and whilst terminated with a SMA-Male connector as standard, other connector terminations are possible. The MP-RTK antenna has an integrated LNA with approximately 37 dB effective gain for GPS L1, 36 dB effective gain for GPS L2 and 32 dB effective gain for GPS L5 thereby offering high gain performance.
