New NovAtel system combines GNSS+INS in small package

July 10, 2018  - By

NovAtel is now delivering its SPAN tightly coupled GNSS+INS navigation technology in a rugged, ultra-compact unit.

Commercially exportable and designed for integration into a wide variety of applications, the high-performance SPAN CPT7 delivers assured positioning anywhere, in a package one-quarter the size of the company’s SPAN-CPT.

SPAN technology leverages generations of precise positioning expertise and advanced algorithms to tightly couple GNSS and inertial navigation system (INS) measurements. The system enables continuous, robust positioning and fast reacquisition in challenging navigation environments where GNSS signals may be unreliable or unavailable for short periods.

The new SPAN CPT7 also incorporates dual antennas to deliver instant alignment, along with interference detection and mitigation using NovAtel’s OEM7 Interference Toolkit (ITK) technology.

Integrators can take advantage of a spectrum analysis function of ITK to identify interference within the GNSS frequency bands and whether interference is coming from the external environment or due to other components in an integration project, NovAtel said. Mitigation features within ITK allow developers to implement digital filters and eliminate the problem.

Combining the multi-frequency, multi-constellation technology of the OEM7720 receiver board with ITK and the high-performing micro-electromechanical systems (MEMS) IMU, the SPAN CPT7 delivers anti-jamming functionality in an ultra-compact enclosure that fits in the palm of your hand. When paired with the GPS Anti-Jam Antenna (GAJT) in military applications, SPAN CPT7 is an integral part of assured position, navigation and timing (A-PNT).

“The remarkable new SPAN CPT7 delivers solutions for defense, mobile mapping, and autonomous vehicle applications with more flexibility than ever before,” said Neil Gerein, director, product management, NovAtel. “This new product saves customers space and weight without compromising accuracy or performance.”
