MGI implemented MACS in High Level and Zama to improve the accuracy and efficiency of all our northwestern Alberta surveys. MACS uses a wireless high-speed internet connection, two unattended GNSS tracking stations (active control stations), Leica Geodetic satellite receivers, Geodetic Antennas, broadband internet connections, and Leica GNSS Spider software. The two active control stations continuously record one-second data from all tracked GNSS satellites above a mask angle of 10 degrees.
MACS Zama and MACS High Level are monitored from Calgary through a high-speed internet connection. These links ensure that continuous and reliable data is available to MGI. The system enables our survey crews to confirm field positions in northwestern Alberta from a single receiver in the field because the other receiver required to provide differential accuracy on a known coordinate point is already positioned and collecting satellite data 24/7.
Observational data from our active control stations is recorded and maintained at the MACS central processing facility in Calgary and supports the integration of our surveys with the Canadian Spatial Reference System (CSRS), the Alberta Survey Control Network, and Alberta Township baselines.
MACS is integrated with the Alberta Survey Control Network, and our 2nd Order active control stations in High Level and Zama are ASCM No. 320266 and ASCM No. 490540, respectively. The High Level station is a static and RTK master 24/7.
MACS eliminates the time-consuming procedures required to erect reference stations, download reference survey data, and integrate surveys into a survey network, thereby reducing costs to clients by improving our survey productivity, accuracy, and reliability.
