GPS Repeaters For Agriculture
When parked inside a building, precision agriculture machinery can’t receive a GPS signal due to the blocking effect of the building structure.
This means the machinery has to be moved outside to get a view of the sky so that GPS systems can be tested after installation or repair.
Another consequence of being under cover is that when a machine is moved outside again, it can take several minutes for the acquisition of satellite signals to provide a fix.
The problem is that the GPS signals, having travelled 12,500 miles from the satellites in orbit above the Earth, are too weak to penetrate the building structure.
A GPS repeater system installed in a farm building or manufacturing plant ensures that:
- All equipment receives a “live” GPS satellite signal whilst indoors.
- Satellite-guided farming equipment is “locked on” to the GPS satellites at all times when indoors.
- When machines leave the building they already have GPS lock and are “ready to use”.
- There is no prolonged wait for satellite acquisition to happen when leaving the building.
GPS repeater installation guide
- A receiving antenna is placed where it has the best possible view of the sky, generally on the roof. This ensures it can “see” as many satellites as possible.
- The signal propagates down a coaxial cable into a repeater unit that re-radiates the signal into the indoor space.
- A single repeater unit can provide indoor coverage over a radius of approximately 35 – 40 metres when mounted at a height of 10 metres.
- Repeater equipment is available in standard moulded plastic boxes, or in IP67 waterproof enclosures.
Further Information
A repeater kit comes with all you need to get indoor GPS signal in your building.
For larger areas where one single repeater is not enough we can offer you a custom-designed-system to meet your exact requirement.
