Radio Handles – interference with Bluetooth devices Bluetooth devices are used for short-range personal area networks operate from 2.4 to 2.4835 GHz. Similarly, RH1200/RH15 radio-modems use the frequency range 2.4 to 2.5 GHz. To avoid interference, Bluetooth protocols divide the band into 79 channels (each 1 MHz wide) and changes channels up to 1600 times per second. Newer Bluetooth versions...

In a recent accident involving a GS15 reference antenna, the ‘I-beam’ design withstood an 8m fall from a roof-top mount, down to a gravel surface. All associated accessories were destroyed, however the antenna itself continued to track! Rated IP67 and designed to “withstand a 1.0 m drop onto hard surfaces”, the kit continued to function for the duration of the...

Topcon GMS-2 / GRS-1 users – changes to TOPNET As part of the ongoing improvements to the TopNET Network RTK service, we have been advised to migrate all Topcon GNSS users to a different server. This means that you will need to change the existing IP address: 94.236.29.170/2101 to the following: 94.236.29.172/2101 (only one digit will change). To do this...

Distance dependant errors – but my prism type is correct Leica’s range of total-station instruments have the option to apply a scale-factor to the EDM distance measurement. For small sites, where scale-factors are not used, this EDM-setting can be ignored (the default is 1.00). However, on those rare occasions when your free-station just doesn’t quite resolve to a few mil...
