Electronic Navigation: Survey navigation is provided by a LiNav-3D system from Ag-Nav Inc. The system consists of an integrated computer/monitor/keypad and a colour LED digital pilot display (array of 28 by 30 lines) that shows horizontal cross-track and vertical elevation simultaneously along with other pertinent navigation information. The primary GPS receiver provides the system with real-time corrected horizontal and vertical positional information for precise guidance along the pre-programmed survey flight grid. For 3D drape flying an elevation grid is input which has been calculated from a digital elevation model (DEM) and the aircraft climb characteristics. Vertical input to the system can be GPS altitude or radar altimeter.

Radar Altimeter: The radar altimeter is a FreeFlight TRA-3000 coupled with a TRI-40 digital indicator. The altimeter has a range of 40 to 2500 feet and an accuracy of 5%. Output is analogue.

Digital Video Flight Track System: A Stack DVR3-130 digital video & data recorder with input from a colour video camera mounted in the belly of the aircraft is used to record the ground track of the survey aircraft. The DVR3 is a compact solid-state video recorder with data input from the primary GPS receiver. The date, GPS time in seconds, latitude and longitude position are overlain on the video image on the top left side of the video frame. The video files are recorded as mpeg-2 compressed files with a separate file per survey flight line.
