Description

technical field [0001] The invention relates to a test device, in particular to a GNSSMARK simulation test device based on a single-chip microcomputer. Background technique [0002] With the rapid development of high-tech surveying and mapping technology represented by 3S technology and computer technology, the traditional surveying and mapping industry is rapidly transforming into geographic information industry. The main mode of traditional surveying and mapping production has undergone fundamental changes. Products have changed from analog to digital. A large number of field surveys have been replaced by indoor geographic information collection represented by UAV photogrammetry. The collection, storage, processing and release of geographic information has become a new concept. [0003] Since the Beidou networking, as an independent emerging measurement technology has been widely used in the field of measurement, UAV aerial photogrammetry has pushed Beidou to another appl...

Problems solved by technology

In the early test method, the GNSS high-precision positioning mobile terminal equipment was installed on the drone, and then the actual flight test was carried out in the field. This method has a large workload, high cost, and low efficiency, which seriously affects the mass production and large-scale application of the product. ; Later, the short connection method of direct connection wires was adopted, and the positive and negative poles of the signal of the equipment under test were connected by hand, and pulses were generated manually, and counted by manual counting. Manual counting once, may actually be short-connected many times due to jitter, it is difficult to accurately determine the actual count of the device under test, on the other hand, the time for manual counting is long, it is easy to make mistakes, and the actual synchronization time record of the device under test cannot be accurately tested stability
