- We use the accuracy of less than 15 meters, the Americans themselves can be very highThe use of GPS positioning, will be affected by a variety of factors. The factors affecting the accuracy of GPS positioning with GPS satellite can be divided into the following four categories:(1) SA from the U.S. government interests, by reducing the precision of broadcast ephemeris (Technology), adding high frequency jitter in GPS reference signal (Technology) and other methods, reduce the ordinary users using GPS navigation and positioning accuracy.(2) the satellite ephemeris error in GPS positioning, calculation of satellite orbit parameters at a time the GPS satellite position required is provided by various types of [7] ephemeris, but irrespective of the type of ephemeris, the calculated satellite location will be its true position difference, this is the so-called ephemeris error.(3) the satellite clock error of satellite clock error is the error between the installation on the GPS satellite atomic clock clock with GPS standard time.(4) satellite signal transmitting antenna phase center deviation satellite signal transmitting antenna phase center deviation is the difference between the nominal phase center and the true phase center of the signal transmitting antenna on the GPS satellite.
- Q:Which kind of GPS locator is better, generally how much money?
- This is only more than and 100 you can go to see Huizhi Albert PG02 Alibaba,Shenzhen, okay, I spent almost a year.

- Q:How to pay for the satellite locator on the car, how much to pay?
- Direct charge to the flow of the card can be, as the phone recharge
- Q:At present, the accuracy of civil GPS in the end is how much?
- The navigation accuracy of GPS type belongs to the single point positioning accuracy, probably between 3~15 meters; high precision measurement of GPS generally refers to the accuracy of RTK, to 10 cm; the accuracy of WGS84 coordinates accuracy; usually see vehicle navigation or mobile phone navigation precision is high when there is a map of the correct.
- Q:Why can not locate the vehicle GPS locator
- There are several possible:First: signal interference, GPS antenna near the iron or magnetic field.Second: the shelter, tall buildings, mountains and basements will cover the satellite signal.Third: time set, time is not allowed or return interval is too long error.My answer to your help please take ah!
- Q:Just burglary was not a very expensive mountain bike, intends to buy a car with GPS, please recommend a few easy to use micro GSP locator, a treasure on the more complex, a few requirements:As small as possible, the mountain car is not easy to hide.Life as long as possible, 35 days a charge that is not convenient to use.Don't seven hundred or eight hundred ha, cheap point.
- For several years without contact, you still choose it, you want to save electricity, then you can not set the background to the general requirements of the boot, and then re boot the boot location.
- Q:Children's GPS positioning mobile phone watch need to install a phone card
- It comes with a watch,Is an external card is inserted SIM card.The general is more than the card, do not have the card, personal feel or card is better, then do not want to use the card can also be used on the phone.Currently on the market positioning GPS watches are SIM card positioning, which is the positioning of GPRS, base station positioning.
- Q:Car G P S locator day launch a signal
- The way the automotive GPS locator after the receipt of goods traffic card into the card slot equipment, electricity, see blue light after representing the location, then you can use the account and password.
