There's a few little tweaks to be found in the December release of Leica's SmartWorx Viva v6.13 and Captivate v2.13.
Captivate will now support a new high powered base radio (HPR3) for those using GNSS systems over a long range. There's also a new Bearing and Distance app which allows a point to be computed by defining a bearing and distance from an existing point, and the addition of four new variables to the Stake tunnel and Check tunnel HTML export.
In SmartWorx Viva there's improvements in dealing with the latest additional leap second as well as new measurement engine software for the GS10/14/15/16 receivers, and a host of bug fixes.
