GPS Positioning All The Time, Throughout the Mine
Machine applications aimed at boosting mine productivity and efficiency rely on accurate and available Real-time Kinematic (RTK) GPS positions. Accomplishing this typically requires tracking of a minimum of four satellites with good "geometry," a condition often not met in deep, open-pit mines.
24/7 Availablity
The Terralite™ XPS System solves this availability problem using a network of ground-based transmit stations. By broadcasting a proprietary new signal, called "XPS," to one or more mobile GPS+XPS receivers, operators of GPS-enabled machines can benefit from continuous real-time positioning information, when and where GPS can't. Incorporating state-of-the-art positioning and radio frequency technology, the system combines portable, free-standing Terralite transmit stations with a new category of tri-frequency GPS+XPS capable receivers.
Tri-Frequency (L1/L2/XPS) Coverage
With a network of Terralite transmitters broadcasting a new, independent positioning signal called "XPS," mine operators can compute accurate 3 dimensional positions in locations that standard GPS alone can't reach, such as in pits where satellite signals are blocked by steep highwalls. Standard positioning outputs support the most popular GPS-enabled applications already running in the mine – so with Terralite XPS, the only big change is your up-time.
System Benefits:
Mine operators will experience many benefits from Terralite XPS, including:
- Up to 100% position coverage, deep in the mine
- Compatible with any application utilizing GPS
- Easy setup with self-surveying transmitters
- High-performance in both static and mobile environments
- Scalable, simultaneous support for unlimited mobile units
Positioning Infrastructure and Receivers
Terralite XPS Transmit Station
Terralite XPS utilizes special ground-based transmitters, the Terralite positioning infrastructure, to form an independent, yet GPS interoperable, positioning infrastructure for the mine.
Terralite GPS+XPS Receivers
Developed for machine guidance, control, and surveying applications, the GPS+XPS receiver is capable of fast, low-latency positioning.
Terralite XPS Reference Station
The Terralite XPS Reference Station is a key component of the positioning infrastructure, providing L1/L2 RTK data plus XPS signal information to mobile receivers.
XPS eXtended Positioning Signal
Broadcast by a network of Terralite transmit stations, the revolutionary new XPS signal is used by GPS+XPS receivers to compute fast, low-latency positions on any number of mobile machines - even without GPS.
