Quick Start Video: Precis-BX305 GNSS RTK Receivers

Precis-BX305 is a compact GNSS positioning solution offering real-time, cost efficient centimeter-level positioning capability as well as flexible interfaces for a number of applications, such as navigation, precise agriculture, surveying and UAV.

The compact positioning system Precis-BX305 can be integrated to other host devices or served as an independent positioning system, which is dedicated to deliver high precision, reliable positions between rover and the reference antennas. It uses standard serial port or UHF module for communication. A PicoBlade connector makes it easy to integrate to its host devices or autopilots. The Precis-BX305 board supports multi-GNSS RTK positioning, which improves the continuity and reliability of RTK positioning.

This quick start video provides basic instruction for setting up and suing Precis-BX305 RTK Solutions. For details, please refer to Precis-BX305 User Guide.

What is CORS network? How to connect to CORS network with external Bluetooth module and mobile phone?

A CORS is a Continuously Operating Reference Station. The CORS is an appealing way to do RTK due to its convenience and large coverage area. While Tersus Precis-BX305 currently does not support build-in NTRIP client feature. An alternative way to connect CORS network is employing external Bluetooth module and a cellphone. Here is a detailed procedure about how to connect to CORS Network with Precis-BX305 board. Demonstration of connecting Precis BX305 to CORS Network Hardware & Software Requirement Precis-BX305 GNSS antenna GNSS antenna cable External Bluetooth module Bluetooth cable Cell phone (android system) 5V DC charger Software required Ntrip client (free android apps) Connect to CORS Network Please follow below steps. Connect GNSS antenna to Precis-BX305. Connect external Bluetooth module to either COM1 or COM2 of the board Connect to power supplier and plug in/turn on the power Turn on the Bluetooth of the mobile phone and scan and pai

What is the principle of GNSS positioning?

Satellite based positioning relies on measuring distance between satellite and receivers. With known satellite position and measured distance between satellite and receiver, the coordinate of receiver can be calculated. However, the electromagnetic signals emitted by satellites are perturbed by atmosphere and clock errors, which degrade GNSS positioning accuracy. There are two types of positioning mode, one is point position and the other is relative position (see Fig 1). Point positioning includes standard point positioning (SPP) and precise point positioning (PPP). Their major difference is whether use the carrier phase observation. Relative positioning also includes two types: DGPS and RTK. Their difference is the latter one uses carrier phase observation as well. Relative positioning cancels most error sources in distance measurement by making difference between two receivers, so it is more simple and reliable, but it only measures relative position. In practice, the coordinate of
