FAQ We provide antenna manufacturers and offer a big range of internal patch antenna which includes GPS patch antenna, ceramic patch antenna and patch antenna design.Q:What is the difference between internal and external GPS antenna?A:The internal antenna is built into the device. The external antenna can be mounted in a remote location. The only reason to use an external antenna instead of an internal antenna is if the device being used will be mounted in a location where it cannot acquire the GPS signal.Q:The picture is real product?A:Yes,all product pictures are real product.Q:If stock quantity is not enough from link, how to do?A: Contact/Leave message to us, we will reply and help check exact stock within 12 hours.

Therefore, GPS outweighs GLONASS in accuracy as lower error numbers are better.Q:Should you use GPS with GLONASS?A:Actually only gps should do its job in case satellite reception is perfect. The combination with another system will improve accuracy when the signal gets weaker.Q:Does GPS work without an antenna?A:GPS (Global Positioning System) systems work by receiving signals from satellites.
