CPT7 Overview

SPAN GNSS+INS technology from Hexagon | NovAtel brings together two very different but complementary positioning and navigation systems namely Global Navigation Satellite System (GNSS) and an Inertial Navigation System (INS). By combining the best aspects of GNSS and INS into one system, SPAN technology is able to offer a solution that is more accurate and reliable than either GNSS or INS could provide alone. The combined GNSS+INS solution has the advantage of the absolute accuracy available from GNSS and the continuity of INS through traditionally difficult GNSS conditions.

NovAtel's CPT7 is a scalable, high precision GNSS+INS receiver in a lightweight, compact, environmentally protective enclosure. There are two hardware versions of the CPT7 to meet a range of GNSS applications.

  • CPT7
    The CPT7 combines a dual antenna OEM7720 receiver and a high performance Honeywell HG4930 IMU in a single enclosure to provide an easy to deploy SPAN GNSS+INS and ALIGN system.

  • CPT7700
    The CPT7700 combines an OEM7700 GNSS receiver and a high performance Honeywell HG4930 IMU in a single enclosure to provide an easy to deploy SPAN GNSS+INS system. In addition to the GNSS signals tracked by the CPT7, the CPT7700 also tracks Galileo E6, BeiDou B3I and QZSS L6.

In this document, the term CPT7 is used to represent both the CPT7 and CPT7700. When a section applies to a specific version, the applicable version is identified (e.g. CPT7 only or CPT7700 only).

The CPT7 and CPT7700 provides the following features:

  • Multi-frequency/Multi-constellation

  • Dual antenna inputs for single enclosure ALIGN heading solution (CPT7 only)

  • SPAN GNSS+INS functionality

  • Two serial communication ports, 1 RS-422 and 1 RS-232

  • One USB communication port

  • One Ethernet communication port

  • One CAN bus port

  • 3 Event outputs (Legacy CPT7 receivers (PN 80023560) provide 2 Event outputs)

  • 3 Event inputs (Legacy CPT7 receivers (PN 80023560) provide 2 Event inputs)

  • Wheel Sensor (DMI) input (not available on Legacy CPT7 receivers (PN 80023560))

  • 16 GB of internal data logging storage (not available on Legacy CPT7 receivers (PN 80023560))

  • 4 status LEDs (not available on Legacy CPT7 receivers (PN 80023560))

  • PPP, RTK, SBAS and DGPS positioning solutions

  • GLIDE and ALIGN positioning options

  • Enhanced interference mitigation

In this document, Legacy CPT7 receiver refers to the previous version of the CPT7. Refer to Differences Between CPT7 and Legacy CPT7 for a comparison between the current and Legacy CPT7.
