smartgnss.store — SmartGNSS OEM receiver

The SmartGNSS receiver has been specially built for agricultural industry. Being installed to agricultural machinery it provides information for precision farming systems, navigation and automatic control. SmartGNSS contains a receiver module and an antenna designed by leading manufacturers which guarantee its high stability and performance.

CONSTRUCTION

The GNSS satellite receiver and antenna are placed in a rugged weather-resistant plastic housing manufactured using automotive grade plastic. The device is equipped with connectors with IP68 grade and has a valve which prevents the accumulation of moisture inside the case when operating over a wide temperature range. The upper part of the unit is made of white plastic to prevent the device from overheating by direct sunlight. Three powerful Ø16mm magnets lie on the lower part of the casing, securely fixing the receiver on any metal surface. The bright multicolor LED Indicator displays all device operation status, navigation mode, radio status.

DESIGNED TO WORK IN THE FIELD

Our internal software not only provides tools for daily use of the receiver but opens up new opportunities for better performance:

AutoBASE makes an easiest way to repeat the setup of RTK base station on a daily basis. It automatically sets the coordinates of the base station for reuse at a fixed point. It is possible to save up to 32 installation points in the memory unit. When point is activated, the software helps to simultaneously adjust the corresponding frequency of the radio module.
CoWORK – supports grouping vehicles (up to 8 units) at one field with real-time monitoring of every unit’s position (requires RTK receiver, radio module and display software support).
ACURATE — proprietary technology provides path to path navigation accuracy lower to 20 cm @ 40 minutes w/o external corrections, it based on advanced GNSS receiver with true raw measurements output. This technology has many years field proven accuracy.

CUSTOMIZATION — OEM

Appearance of the device, its accessories and cables — it all can be customized. The color of the lower part of the case can be made in accordance with the preferences of the customer (the RAL is required, the MOQ is 500 pcs). The inner PCB has no manufacturer ID, so all labels can be designed by the customer. The smart-antenna design allows manufacturer to build a combination of navigation modules, antennas and radio modules required in the customer’s project to achieve the required cost/accuracy/flexibility. The ability to use key components from different manufacturers makes it easier to manage the product lifecycle. The cables will customized on customers’s request, cable type, connector and pin-out.
