Better Performance on RTK Receiver with External Antenna in the Forests
SatLab SLC can track 18–20 satellites in the open air
The SATLAB TOOLBOX application is used for the one-time first configuration of the SatLab SLC receiver to download RTK/RTN corrections.
Power GPS – application for Android:
The test was conducted using the Power GPS application. The Power GPS configuration comes down only to connect the application to the SatLab SLC via Bluetooth.
3 points have been measured to compare the performance of the receiver with an internal antenna and with an external antenna. Below is a table with deviations.
Tests in forest areas
In the forest, the receiver only works with an additional external antenna. The position accuracy is 2 cm. When moving with the receiver, the accuracy is about 15–20 cm. It is necessary to stop for a few seconds to get an accuracy of 2 cm again. Below are the screenshots from the application and photos from the measurement place.

CONCLUSIONS:
GREAT PERFORMANCE
SatLab SLC works very well. It searches satellites quickly: in the open air, it can track 18–20 satellites. When equipped with an external or an internal antenna in open areas, it can provide good accuracy and quick initialization and stable connection, especially the high recurrence of the accuracy of measured points. The external antenna amplifies the signal. There is a visible difference from the measurement without the antenna between the buildings and in the forests, while in the open spaces, measurements can be taken without an additional antenna.
SIMPLE OPERATION AND CONFIGURATION
You need to configure the SatLab SLC Toolbox once only and it will remember all settings. Therefore, from the second time, all you need to do is to switch it on and to connect to a measuring application on your tablet or smartphone.
