Abstract: As we all know, the normal operation of agricultural machinery automatic driving navigation is based on high-precision location services, the earliest portable radio base station and some high-power radio station fixed differential station, after the transition to the network type base station, but more than a single station, the service range is limited to a single link, if the failure or power outage, the base station covers the area of all the equipment can not be used, at this stage, more than a CORS service, the terminal base station The current stage is mostly CORS service, terminal base station to provide services, improve the stability of the service and expand the coverage.
The most powerful thing about Star-Land One series of agricultural navigation is that it has signal anywhere in the country, even in the remote Gobi Beach, because Star-Land One series of navigation adopts Star-Land fusion technology, which solves the signal problem completely, and it broadcasts the service of differential signal through the satellite, so that in China, as long as the satellite is visible, you can get the centimeter positioning service of thousand searches, which solves completely the problem of relying on the network to operate the navigation for the agricultural machinery.
Effectively solve the problem of high-precision service blind area, a set of equipment at any time and anywhere operation, neither need to consider the region 4G signal there is no, good or bad; also do not need to hold the left hand to carry the base station, the right hand carrying a battery, but also always worry about the base station charging, battery out of power and other issues.
As we all know, the normal operation of agricultural machinery automatic driving navigation is built on the basis of high-precision location services, the earliest portable radio base stations and some high-power radio station fixed differential station, after the transition to a network-based base station, but more than a single station, limited range of services, a single link, if the failure or blackout, the base station covers the area of all the equipment can not be used, the current stage of the more CORS services, terminal base station network Provide services to improve service stability and expand the coverage area. However, CORS service is built on the basis of the network, for agricultural application scenarios there are still many no network and weak network environment, signal loss is a big problem.
For users, signal loss, you have to use manual driving farm machinery, or simply "be" suspended operations.
The biggest advantage of the star-ground integration is to solve the no-network or weak network environment can still provide high-quality high-precision location services, wider signal coverage, higher availability, better user experience.
Especially in the remote areas of Heilongjiang, Inner Mongolia and Xinjiang provinces, the communication network coverage is not good, the cell phone signal is not good or there is no signal at all, the use of agricultural machinery navigation is limited, often giving users a headache, no edge of the convenience brought by the automatic driving of agricultural machinery, Chance location of star-ground all-in-one perfect solution to the problem, no longer worry about the signal problem.
Chance star-based service, the initialization time is very short, the fastest can be 50 seconds - 2 minutes, after fixing the accuracy of 2.5 cm, to meet most of the scenarios user needs. Star-based agricultural navigation at home and abroad has been a high-end monopoly, and we have launched the "star-ground integration" high-precision location services in order to signal a better experience.
For agricultural navigation is the most core, the most critical signal. Signal is guaranteed to ensure that the operation of the orderly start and carry out operations; only on the basis of signal stability, the system can accurately control the steering, to protect the accuracy of the operation, reduce land waste, thousands of navigation, efficient farming must be.
