A GNSS/INS system typically includes a 3-axis gyroscope, a 3-axis accelerometer, a GNSS receiver, and sometimes a 3-axis magnetometer to estimate a navigation solution. Each of these sensors contribute different measurements to the GNSS/INS system.

GPS/INS is the use of GPS satellite signals to correct or calibrate a solution from an inertial navigation system (INS). The method is applicable for any GNSS /INS system.

Which inertial navigation system works best with GNSS? Why are inertial measurements beneficial to GNSS? Learn from our Intro to GNSS book.

A GNSS + INS (Inertial Navigation System) receiver fuses a multi-frequency GNSS receiver with an industrial-grade IMU sensor to provides reliable centimeter-level positioning together with attitude/orientation angles including heading, pitch and roll.

NovAtel's SPAN technology deeply couples our OEM precision GNSS receivers with robust Inertial Measurement Units (IMUs) to provide reliable, continuously available, position, velocity and attitude-even through short periods of time when satellite signals are blocked or unavailable. Combined Systems. Compact, single enclosure GPS+INS system.

A GNSS Compass/INS, or Dual GNSS/INS, consists of two onboard GNSS receivers, forming a GNSS compass, and an onboard inertial navigation system (INS).

Most commercial INS systems also incorporate GNSS sensors to enhance accuracy. GNSS, such as GPS, provides absolute position information, which can be used to correct or validate the position and velocity estimates obtained from the IMU. This combination is known as sensor fusion. GNSS Receiver

Each INS contains Inertial Labs developed Tactical or Industrial-grade Inertial Measurement Units (IMU) and reliable single or dual GNSS receivers from suppliers like NovAtel, u-blox, and Septentrio.

Inertial Navigation Systems (INS) determine a vehicle’s position, velocity, and orientation using motion sensors (accelerometers and gyroscopes) and a GNSS receiver, without the need for external references.
