Everyone can use RTK - Tersus GNSS Inc.

[Everyone can use RTK] Satellite based positioning relies on measuring distance between satellite and receiver. There are two types of positioning mode, one is point position and the other is relative position. Real time kinematic (RTK) positioning is a kind of relative position. Relative positioning cancels most error sources in distance measurement by making difference between two receivers, so it is more simple and reliable. RTK can be used in challenging environments where there is high interference, multipath effects and occlusions.

For surveying or GIS-related applications, the traditional requirement for positioning accuracy was at meter or sub-meter level, in static mode. However, emerging applications such as UAV surveying & mapping not only require high precision at centimeter level, but also operate in moving, kinematic modes. RTK is not yet deployed in surveying and mapping on a large scale. The cost is still high. The rapid development is bringing RTK technology to a broader market. As a result the price will become more attractive.

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 mobil...

How to Use Oscar to Collect Static Data for A Given Length of Time

Usually, we need to collect static data for a given length of time, for example, 2 hours. In the past, the surveyor had to record the start time and keep an eye on the clock all the time. The function of setting the static collection duration in Oscar GNSS Receiver can solve this problem. When setting the static survey, the surveyor only needs to enter the duration time, then start it, and no more attention will be required. When the time is up, Oscar will automatically stop recording, with no fewer or more data. Now we show you how to set the Oscar static collection duration on the OLED display of Oscar. 1. Turn on the Oscar, press the Power ON/OFF button and Function (FN) button, and go to Mode Config -> Static. The default option of Static is OFF, and you can press the Function (FN) button to switch it to “Auto” or “Manual”. 2. Go to Duration to set the collection time, for example, 120 minutes. 3. Set other options, then choose “Confirm”, and it will start to collect st...
