Can Precis-BX316 work well for aerial photogrammetry with UAV without the need for ground control points(GCPs)?

Can Precis-BX306 work well for aerial photogrammetry with UAV without the need for ground control points(GCPs)?

Yes, the following solution can be used to replace the GCPs:

You can setup a base with our Precis-BX306, and then transmit RTK corrections from the base. After the corrections are received, it will output accurate (cm-level) positioning and heading info. In the application of aerial photogrammetry with UAV, after the camera take a picture, it will send a pulse from the PC (Prontor-Compur connection) port to the receiver, the accurate position (cm-level) will be saved.

The photos and their positions will be input to the mapping software (eg, PIX4D or Agsoft) to get an accurate map.

Do I need a specific camera to work or any camera?

No specific camera is needed; you can use any camera which has a PC (Prontor-Compur connection) port. And the synchronization between the shutters to the flash must be enabled. When the camera is taking a photo, a pulse is sent to the receiver through the PC port. The exact time when the photo is taken will be saved for post-processing.

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...

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...
