It searches satellites quickly: in the open air, it can track 18\u201320 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.<\/p>\n<h4>Simple operation and configuration<\/h4>\n<p>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.<\/p>\n<h4>ABOUT SATLAB GEOSOLUTIONS AB<\/h4>\n<p>SatLab Geosolutions is a Swedish based global satellite positioning solutions company with of\ufb01ces strategically located around the world.
