GPS locator does not return data through the operator
- It is only in a certain range (such as 10km) using the short distance wireless communication, which does not require the support of GPRS, like a battlefield combat squad is much too far away? Only with high power directional antenna or satellite antenna.s

What's the difference between AGPS and GPS?
- AGPS is a network aided positioning, is in no use when the GPS satellite signal, GPS must have AGPS, and not necessarilys
The difference between the built-in antenna and external antenna of GPS positioning equipment
- Built in antenna, is a device and an antenna, the antenna in the device, the appearance of such equipment will generally be relatively small, but how much will affect the signal reception;External antenna: separate equipment and antenna device consists of a host, a signal line, power line, this kind of equipment for external signal line, can be placed closer to the sky outside the range, so the signal and stability will be much better, the accuracy will be better.s
What is the role of GPS
- Application of GPS in road engineeringApplication of GPS in highway construction, the road works mainly for the establishment of control network and the determination of aerial control point. With the rapid development of highway, puts forward higher requirements for the survey, due to long lines, few points to know, therefore, measured by conventional means of distribution network not only difficult, but it is difficult to meet the requirements of high precision. At present, China has adopted GPS technology to establish high-precision control network line head, encryption and then use conventional methods laid wire. Practice has proved that in the range of tens of kilometers of the position error is only about 2 cm, to conventional methods is difficult to achieve the accuracy, but also greatly advance the control measure the duration of.GPS technology is also used in large bridges. Because no visibility, can constitute a strong network, improve the precision of point at the same time, the fulcrum of routine measurements of detection is also very effective in.GPS Technology It has a wide application prospect in tunnel measurement, GPS measurement no visibility, reduce intermediate links, so the conventional method, high speed and high precision, which has obvious economic and social benefits.s
