CHCNAV (Shanghai Huace Navigation Technology Ltd.), a global geospatial technology company providing affordable precision agriculture solutions among other allied technologies, offers high-precision automated steering for accurate and efficient farming

According to CHCNAV, automated steering systems have been widely deployed in advanced economy countries and on large farms to improve agricultural productivity. However, technological and price barriers have constrained a wider adoption. Farms are embracing precision farming to boost productivity, environmental sustainability and economic competitiveness. 

The company opines, with reliable RTK positioning and the expected accuracy of automated steering systems, farmers can optimise their work efforts, reduce input costs and fuel consumption.

Reliable accuracy and multiple RTK sources

CHCNAV's customer, Niva LLC in Voronezh (Russia) was particularly interested in acquiring an automated steering system that is able to provide consistently high accuracy, even in scattered fields over long distances and with unstable GSM coverage. Some systems that were tested often lost GNSS RTK network correction signal reception while working in difficult terrain with gullies. A dual GNSS RTK correction source was therefore a key technical feature to ensure an uninterrupted auto-steering operation in all-terrain configurations.

The CHCNAV NX510 SE's built-in connectivity modules include a 4G modem and an additional UHF radio module to allow farmers to work with RTK correction sources from local RTK networks or GNSS RTK base stations for no additional cost. As a result, the NX510 SE can receive GNSS RTK corrections from various GNSS network operators as well as from a local radio modem input to compensate for possible poor GSM coverage.  The system's combined GNSS+INS terrain compensation technology ensures an automated steering accuracy of 2.5 cm and offers superior performance in ditching, seeding and harvesting applications.

Affordability and portability

According to Niva LLC, the company was also looking to optimise its investment by selecting an auto-steering system that could be quickly and easily mounted on a variety of tractors and other farm vehicles at a price that would allow for quick payback. 

CHCNAV’s NX510 SE is designed to be highly adaptive and can be moved from one tractor to another in less than 40 minutes, as the farming operations change. The software's user interface (UI) is specially built for controlling field operations, which is designed for both experienced and novice operators to allow greater flexibility.

CHC Navigation said it invites potential dealers from different countries to apply for cooperation. The company aims to communicate openly and frequently, to build mutual trust, and help generate larger gains for every dealer.
