Description
Technical field
The invention belongs to the technical field of GLONASS, and in particular to a kind of offer precise relay position in real time
Satellite-signal retransmission unit.
Background technology
GPS (GNSS) is a kind of space base radio-navigation positioning system, can at the earth's surface or closely
The user in ground space provides that accurate three-dimensional coordinate position, tested the speed, time service etc. is serviced.GPS (GNSS) is main
It is made up of the GNSS receiver of the GNSS satellite in being distributed on high and ground, GNSS satellite constantly launches navigation message (GNSS
Signal), GNSS receiver receives navigation message (GNSS signal) and carries out resolving the information such as acquisition time, position coordinateses.The U.S.
GPS satellite navigation system (Global Positioning System), Muscovite GLONASS (GLONASS) satellite navigation
Galileo (GALILEO) satellite navigation system of system, the Big Dipper (BD) satellite navigation system of China and European Union is the world today
Four big GPSs.
Satellite navigation signals retransmission unit is that GNSS signal with tracking lock GNSS signal and can be forwarded to nothing by one kind
Method receive GNSS signal or GNSS signal weaker where communicator, guaranteeing GNSS receiver without GNSS signal or
GNSS signal can also be received where GNSS signal is weaker, for debugging, scientific research etc..
Fig. 1 is the structural representation of traditional satellite-signal retransmission unit, as shown in figure 1, which is mainly by reception antenna, letter
Number transponder and three part of transmitting antenna composition, reception antenna receive GNSS signal, and signal repeater is filtered to GNSS signal
Ripple, amplification etc. are processed, and transmitting antenna launches GNSS signal.When general satellite navigation signals retransmission unit works, reception antenna is pacified
Be mounted in GNSS signal good where, for example outdoor open ground, transmitting antenna is installed in cannot receive GNSS signal or GNSS letters
Where number weak, such as in debugging Factory Building.GNSS receiver is believed by receiving the GNSS of satellite navigation signals retransmission unit transmitting
Number, GNSS signal is received as GNSS receiver is placed on satellite navigation signals retransmission unit reception antenna location.
GNSS receiver resolves the position seat of the position coordinateses for satellite navigation signals retransmission unit reception antenna of GNSS signal acquisition
Mark, this coordinate are referred to as the forwarding position coordinateses of satellite navigation signals retransmission unit.
Fig. 2 is the structural representation of traditional signal repeater, as shown in Fig. 2 which is mainly by prefilter, amplification
Device, postfilter and numerical-control attenuator composition.The GNSS signal that prefilter is mainly received to reception antenna is another
Secondary be filtered process, the noise outside band is suppressed again, it is ensured that amplifier below enters the hand-manipulating of needle to useful frequency
Amplification to property.Amplifier mainly plays the processing and amplifying to GNSS signal, generally broadband amplifier.Postfilter master
If processing to the frequency-selecting that the overall GNSS signal that amplifies after amplifier is carried out again.Numerical-control attenuator is mainly root
According to requirement of the actually used scene to different gains, GNSS signal is decayed.
Satellite-signal retransmission unit in use, often not only will give GNSS receiver provide GNSS signal, also provide
The accurate position coordinateses for forwarding position coordinateses, using provided forwarding position coordinateses to obtain with GNSS receiver positioning calculation
Relatively debugging, test GNSS receiver functional performance etc..Traditional satellite-signal retransmission unit cannot provide forwarding position and sit
Mark, existing solution mainly has following two：When the first, using satellite-signal retransmission unit, its reception antenna is erected at
(position seat is typically built and provided to the point of known location coordinate to the earth standard point by national Mapping departments or its unit that specifies
Mark), the forwarding position coordinateses of such satellite-signal retransmission unit are the position coordinateses of the earth standard point, it is possible to use the earth standard
The position coordinateses of point receive the position of the GNSS signal positioning calculation acquisition that satellite-signal retransmission unit is forwarded with GNSS receiver
Coordinate is relatively debugging, test GNSS receiver functional performance etc.；2nd, power splitter is added in signal repeater, will receive day
The GNSS signal that line is received is divided into two-way, and GNSS signal calculates position coordinateses and by MCU moulds by GNSS receiver all the way
Block display location coordinate in display module, another road GNSS signal is filtered, amplify and then forward, and this kind of improved defends
Star navigation signal retransmission unit structural representation is as shown in Figure 3.Chinese utility model patent ZL201220526529.3 is exactly base
A kind of gps signal transponder for showing and forwarding position coordinateses is proposed in this principle.
Existing scheme one can provide accurate forwarding position coordinateses, but forward position be fixed on the earth standard point
On, accurate forwarding position coordinateses just cannot be provided in real time when the reception antenna of satellite-signal retransmission unit is moved；Existing side
Satellite-signal retransmission unit described in case two, can provide forwarding position coordinateses in real time when its reception antenna is moved, but by
GNSS receiver in satellite-signal retransmission unit obtains forwarding position coordinateses using One-Point Location mode, it is impossible to ensure to forward
The precision of position coordinateses, can only provide the forwarding position coordinateses of meter accuracy.
