Ground-penetrating radar (GPR) is a geophysical method that uses radar pulses to image the subsurface. This nondestructive method uses electromagnetic radiation in the microwave band (UHF / VHF frequencies) of the radio spectrum, and detects the reflected signals from subsurface structures.round penetrating radar survey is one method used in archaeological geophysics. GPR can be used to detect and map subsurface archaeological artifacts, features, and patterning. GPR depth slices showing a crypt in a historic cemetery.
A GSM GPRS tracker is perhaps the most popular type of GPS data tracker available today. A GSM sim card is inserted into the GPS tracker which allows the device to transmit wireless data through a network (like ATT and T-Mobile) to a wireless access point or APN.The APN connects to the internet and transmits the data to a GPS service providerâs server, where tracking data is made available to the end user.DMA trackers, are a little different than a GPRS GSM tracker. Most CDMA gps trackers are equipped with the gpsOne Qualcomm chipset. When compared to GSM trackers, the gpsOne chipset does not appear to be as accurate as its counterpart.
