The configurable stack pairs Javad’s multi-constellation receivers with a choice of commercial or defense-grade IMUs, letting integrators keep producing position, velocity and attitude data when GNSS is degraded.
Javad GNSS on Aug. 12 introduced a new GNSS+INS product line built to keep navigation systems operating when GPS signals are jammed, spoofed or denied.
The US-based receiver manufacturer built the line by pairing its multi-constellation GNSS receivers with commercial and defense-grade IMU modules through a purpose-built interface board, creating a turnkey navigation system for OEMs. The board manages the electrical connection, time synchronization and data path between the receiver and IMU, work integrators previously had to handle themselves when sourcing components separately, choosing instead between a sealed GNSS+INS box built around a single fixed inertial sensor or a fully custom integration effort.
A Configurable Inertial Choice
The inertial sensor remains a configurable choice rather than a fixed component, letting Javad match the IMU to a program’s grade, dynamic range and cost requirements without compromising the performance of the underlying GNSS unit. Current configurations support gyro dynamic ranges up to plus-or-minus 2,000 degrees per second, in-run gyro bias stability between 0.7 and 2 degrees per hour, and accelerometer ranges from plus-or-minus 8g to plus-or-minus 40g.
Gary Walker, executive vice president at Javad GNSS, said the configuration means integrators “can get GNSS performance and anti-jam protection” while still choosing the inertial sensor that fits their program.
Javad designs and manufactures its GNSS receivers in-house at its San Jose, California facility, building on the company’s proprietary TRIUMPH ASIC technology, which the company has marketed for its patented spoofing and jamming detection since introducing the chip’s high channel-count architecture roughly a decade ago. The GNSS+INS configuration is available now for evaluation and integration by qualified users.
