Description
Technical field
The utility model relates to the servicing unit that GPS measures, and especially relates to a kind of GPS and measures angle, room holder device.
Background technology
GPS technology is in survey field widespread use, and its unique advantage facilitates surveying and mapping technology and develops by leaps and bounds, and impels topographic efficiency greatly to improve.Application kinematic GPS technology equipment carries out topographical surveying, is grasped by vast surveying and mapping unit.But house measurement and cadastral survey real estate surveying are due to measuring method and thinking in topographical surveying, cannot measuring accuracy be met the requirements of and be subject to using restriction.
GPS is generally plate-like, and its bottom centre connects centering rod, and namely its geometric center is the center measured.Itself and measured point is only had to project to overlap surveyed coordinate data to be only accurately.When applying GPS receiver carries out house mapping, the contradiction that its measuring center cannot overlap with measuring point projection centre can be run into.Measuring general house can only lean against on angle, room by GPS, such one side body of wall has blocked most of satellite-signal, there is the error of more than half GPS diameter on the other hand, if GPS was lifted roof, instrument tilts to rock existed error equally.Some houses band eaves, does not have satellite-signal under eaves, cannot measure, and GPS was lifted roof eyesight and project, its error is larger.Current measuring method is especially not suitable with the accuracy requirement that the mapping of 1:500 large scale topographical map and cadastral survey and real estate surveying are measured house.
Summary of the invention
In view of above prior art Problems existing, the utility model provides a kind of GPS to measure angle, room holder device.GPS centering rod installs this holder device additional, utilizes support equidistant unambiguous range measurement room angle point fast, reach the object of Measurement accuracy room angular coordinate.
The technical scheme that the utility model is taked is: a kind of GPS measures angle, room holder device, it is characterized in that, described holder device comprises the horizon bar being fixed on the centering rod top that GPS connects, and the front end of horizon bar is provided with locator card angle by turning axle.
Holder device described in the utility model also comprises montant and brace, and the upper end of montant is fixedly connected with the rear end of horizon bar, is fixed on the centering rod of GPS connection simultaneously; The upper end of brace is fixed on the middle-end of horizon bar, and the lower end of brace is fixedly connected with the lower end of montant, is fixed on the centering rod of GPS connection simultaneously.
The beneficial effect that the utility model produces is: 1, this apparatus structure is simply light and handy, and main body is a tripod, or even a cantilever lever, is convenient for carrying.2, improve GPS room angular measurement precision, effectively cannot measure and become half directly measurement.3, the condition of GPS receiving satellite signal is improved.4, adopt this device, GPS leaves house high-wall, receiver can be made larger to empty open angle, can receive more satellite-signals.5, horizon bar can play stable centering rod effect, weakens centering rod and rocks, and makes GPS Received signal strength faster more accurate.6, angle, room can be blocked by quick position in locator card angle, and house re-entrant angle and the straight angle also can be measured in reversion locator card angle.
