Commentary:
Leica Surveying System 300. Leica introduced the system in 1994. The main components include: a GPS receiver, a sensor and a controller. The receiver is set up over the control point. The sensor receives the satellite signals from the receiver. The controller controls the sensor, logs the data and manages the survey operation. The “E” designation in the SR399E receiver means that it also had an external antenna which is shown in the image above.
The Leica Surveying System 300 was produced by the Leica Group. Although the Leica Group was established in 1990, its history goes back 200 years as it was formed from amalgamations of the Wild Heerbrugg, Leitz and Kern companies. In 1997 the Leica Group split into two companies Leica Microsystems and Leica Geosystems. Leica Geosystems today is a leader in producing surveying instruments..
Source of Object: Several Leica Surveying System 300 units were donated by Maltais Geomatics.
