Dual-antenna CPT7 enclosure with GNSS+INS technology

A CPT7 product enclosure with dual antenna ports and four receiver LED status lights on a white background.

The CPT7 is a single enclosure Global Navigation Satellite System (GNSS) + Inertial Navigation System (INS) receiver powered by OEM7 technology from Hexagon | NovAtel that delivers up to centimetre-level accuracy. The dual-antenna inputs provide the user with heading information and rapid alignment of the combined GNSS+Inertial solution. It’s lightweight, ultra-compact and offers a low-power solution with multiple communication interfaces for easy integration on multiple platforms.

The CPT7 contains a high-performing Honeywell HG4930 Micro Electro Mechanical System (MEMS) Inertial Measurement Unit (IMU) to deliver NovAtel’s world-class SPAN technology in an integrated solution. SPAN technology deeply couples GNSS positioning and the stability of IMU gyro and accelerometer measurements to enhance satellite tracking and provide the most continuous positioning solution possible.
