The Kindhelm Connectivity Box (CB) is a rugged, multi-interface communications hub that keeps your RTK-GNSS receiver and all onboard systems online—no matter where the machine is working. It aggregates correction data and backhaul connectivity in one compact unit, so fleets can standardize on a single, durable box for field operations.
At its core, the CB ensures seamless access to RTK corrections from whichever source is available. An integrated NTRIP client connects to network casters, while the optional UHF radio (403–473 MHz) lets you pull corrections from a local base station. The CB then distributes those corrections to your receiver over Ethernet or RS-232, automatically bridging modern and legacy devices.
For backhaul, the LTE Cat 4 modem delivers dependable Internet (up to 150 Mbps down / 50 Mbps up). A built-in Ethernet switch provides 3× LAN plus 1 configurable WAN/LAN port, so you can plug in sensors, displays, cameras—or even an external router such as a satellite link for remote sites. Local access is simple thanks to Wi-Fi (802.11 b/g/n) and Bluetooth 5.2 for configuration, service, and secure wireless AP use cases.
Engineered for harsh duty, the CB operates from −40 °C to +85 °C with industrial-grade M12 and SMA connectors and IP67 protection with mated connectors. It runs on 6–24 V DC, typically under 5 W.
Security and interoperability are built in. The UHF link supports AES-128 encryption and a wide set of professional radio protocols (SATEL and TrimTalk/PacCrest families), helping mixed fleets interoperate without re-wiring vehicles or swapping radios.
Typical deployments include precision agriculture (tractors, implements, field robots), forestry machinery, and other unmanned or guided ground vehicles—anywhere reliable corrections, networking, and service access are critical to uptime. The CB complements Kindhelm’s broader RTK-GNSS and INS portfolio for OEMs and system integrators, aligning with the company’s focus on high-accuracy positioning for mobile applications.
