In B --- several different navigation patterns that can be shown in navigation mode region.Navigation pattern is according to flight progress
And GPS mass is different and different:
1) INS inertial navigation systems
Slide bar, which is shifted onto, can activate this state, this is the simplest navigation pattern that aircraft performs, and most dynamic
State.In this mode, aircraft affected by wind may shift, will on flying distance or the information of current location
It will not show, fly indoors or be subject to GPS can be proper using the pattern when disturbing.
When aircraft detects RC dropouts or do not have magnetometer, INS-red limit risks may be activated.
2) MAG magnetometers
Shift slide bar onto middle potential energy and activate this state, under the navigation pattern, aircraft can be come using the information of magnetometer
Judge the real-time direction of forearm, aircraft affected by wind may shift, on flying distance or the letter of current location
Breath will not be shown, flown indoors or be subject to GPS can be proper using the pattern when disturbing.
When aircraft detects RC dropouts or do not have magnetometer, MAG-red limit risks may be activated.
3) GNSS Global Navigation Satellite System
This is md4 series aircraft acquiescence navigation pattern set under normal operations environment, and aircraft acquiescence uses
Dynamic locks, and helps user to carry out GPS calibration when to instruction, reduces since the influence of wind causes the offset of aircraft, or
The translational speed for the instruction limitation aircraft given according to user.Require there is stable gps signal to receive to maintain this during work
Item navigation pattern.In this mode of operation, aircraft stabilization last instruction point GPS location, only make pitching and
Rolling instruction (or activation destination pattern), GPS location can be just updated.Under the navigation pattern, according to being supplied to system
Instruction, client, which can change, to arrive:MAG, INS, HM and WP pattern.
4) WP destinations
The navigation pattern is also self-driving pattern, because aircraft can be according to the instruction repertoire for setting and uploading in destination path
Perform different tasks.Require there is stable gps signal to receive to maintain this navigation pattern during work.When the navigation pattern quilt
After activation, user is unable to the direction of change of flight, and the control of camera can be realized in itself by aircraft, or user can be
It is first good defined in destination path before flight.
After activating the navigation pattern, aircraft can fly to next destination according to instruction repertoire from current location, on this road
If barrier in line, aircraft may be impacted.
5) mono- keys of HM make a return voyage
The navigation pattern is shown when (human hand or automatic activation) auto-returned takeoff point can be performed in aircraft, is worked
Shi Yaoqiu has stable gps signal to receive to maintain this navigation pattern.The activation of the navigation pattern has three kinds of modes:
Manually:User is maked a return voyage by designated command aircraft.
Automatic 1:When remote-control communication is interrupted in md4 series aircraft course of normal operation, aircraft can be automatically into certainly
It is dynamic to make a return voyage.
Automatic 2:, can be according to the action of different parameter setting aircraft execution under destination navigation pattern.
After the pattern is activated, aircraft can adjust its postbrachium alignment takeoff point (acquiescence), be increased to safe height
(acquiescence 30m) or present level (if present level is more than 30m) is kept, then back flown according to the cruising speed of 5m/s,
Until reaching takeoff point.
When gui interface shows current location and the direction of aircraft in 2D grating maps, can point out to fly using icon
The direction of row device, and forearm positions are indicated with red.2D grating maps are defaulted as takeoff point with red spots, and just
Overlay mark north N, heading is represented with red arrow, and foundation is oriented to the forearm of aircraft.
The use of GUI one of them most important variable observed is exactly GPS accuracy and satellite connection number, both are in F areas
In show:GPS accuracy is shown in the lower section in F areas, such as shows 4.5m, that is, represents GPS accuracy<4.5m, this is md4 series flights
The standard value of device work, it is good that green satellite icon represents GPS accuracy, when real-time precision may as low as alarm levels when,
Satellite mapping target color can become light blue.When display purple background yellow satellite icon, represent that aircraft loses gps signal
Alarm state, when aircraft is not received by GPS information, or the information received is not suitable for navigating, and satellite icon becomes
Into black, background is red, and satellite connection number shows NA, represents unavailable, and precision shows X.Xm, represents GPS accuracy>8.0m.
Aircraft is positioned without reference to point, therefore can be affected by wind, when not having gps signal, it is impossible to maked a return voyage using a key.
Wireless control signal is a fundamental for ensureing the running of md4 aircraft securities, and institute is corresponded to bar chart in G areas
The percentage of received signal strength, aircraft do not receive remote signal, and remote controler, which can sound the alarm, reminds user.
