Tersus Launches David Plus, a Dual-antenna GNSS Receiver with Heading

Tersus Launches David Plus, a Dual-antenna #GNSS Receiver with Heading



#Tersus recently launched its new David Plus receiver, a dual-antenna GNSS receiver which offers centimeter-accurate positioning and heading. It is designed for intelligent transportation, construction, machine control, precision agriculture, and navigation applications.

“David Plus is designed for efficient and rapid integration, the compact, lightweight receiver supports measurements output, it tracks #GPS#GLONASS, and #BeiDou signals,” said Xiaohua Wen, Founder&CEO of Tersus GNSS Inc. “The modular and flexible design can provide robust positioning and heading accuracy in a compact footprint for UAVs and other smaller autonomous projects. As the leading supplier to the precision GNSS receiver market, Tersus is focused on developing easy-to-use and affordable products to support high-precision positioning and heading applications.”

The David Plus GNSS #receiver is built for outdoor environments with IP67-rated enclosure. The compact palm size makes it easy to integrate with various application systems. A 4GB in-built memory is to record data for post-processing conveniently.
The David Plus GNSS receiver supports RTK #positioning mode or #RTKpositioning + heading mode. It supports 384 channels. It’s easy to connect an external powerful radio for long range communication.

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
