Pentax G7N Product review

Based on a powerful GNSS engine with Precise Point Positioning (PPP) capability, the G7N integrates an Inertial Measurement Unit (IMU), wireless data links and a Web UI system management for a complete field solution.
The Pentax G7N has 555 channels for full tracking of all major satellite constellations for fast Fixed RTK initialisation.

IMU

The IMU complements the position solution with full 3D orientation that provides tilt and azimuth for more efficient and accurate surveying.

The integrated wireless data links include a global cellular modem, a full-band UHF radio, Bluetooth and Wi-Fi for cable free operations.

Battery

Two hot-swappable batteries provide continuous operation and a SD Card provides additional memory up to 32 GB.

Traditional serial communication, external power and UHF antenna are included with ports on the bottom of the G7N.

The innovative mechanical design of the G7N features a small and light weight magnesium alloy housing, certified to IP67 standards for all weather use. Furthermore, the product design makes superior access to the battery ports, SIM card and SD Card slots for easy insertion or removal in the field.

Configuration and status are easily reviewed and changed from the on-board Web UI, that is accessible from any PC, tablet or smart phone via Wi-Fi. The Web UI also allows wireless firmware upgrade and data transfer.

Overall, the Pentax G7N combines multiple sensors for a robust and accurate RTK solution for the land survey and GIS markets, with easy wireless access, and flexibility as a base, rover or repeater.
