CORS & Reference Station GNSS Receiver Line Overview in Malaysia: Toksurvey NET660 Series

Across Malaysia's Continuously Operating Reference Station (CORS) networks, ground-based augmentation infrastructure, structural deformation monitoring, and autonomous navigation projects, system integrators require specialized reference receivers tailored to distinct deployment architectures

. Distributed and supported locally by MTM Precision in Puchong, Selangor, the Toksurvey (TOKNAV) NET660 Reference Receiver Lineencompasses four versatile models: the NET660, NET660i, NET660i-H, and NET660i-1U

Shared Core Architecture Across the NET660 Series

All four reference receivers in the NET660 lineup are built upon a unified industrial computing and communications foundation

Linux & ARM Cortex-A7 Platform: Every unit runs an embedded Linux operating system powered by an ARM Cortex-A7 1.8GHz processor.
Standardized GNSS Data & Storage: All models support RTCM 3.X differential correction data, NMEA-0183 position data output, RINEX and custom data logging formats, and 32GB of internal storage.
Industrial Network & Serial Interfaces: Every receiver is equipped with a standard RS232 serial interface (supporting baud rates of 9,600, 19,200, 38,400, 115,200, and 230,400 bps), a standard RJ45 10/100M adaptive Ethernet port, and full cellular connectivity across LTE FDD (B1/2/3/4/5/7/8/12/13/18/19/20/25/26/28), LTE TDD (B38/39/40/41), WCDMA (B1/2/4/5/6/8/19), and GSM (B2/3/5/8) bands.
IP68 Magnesium Alloy Protection: All models feature a rugged magnesium alloy main body with IP68 dustproof and waterproof ingress protection.
