Description
Technical field
The present invention relates to a kind of satellite receiver and receive star method and device fast, but especially search the star method and apparatus fast about satellite receiver portable, the receiving position random variation.
Background technology
China's satellite-signal receives, it is broad because the region area is big, therefore the Electric Field Distribution gradient is big, causing receiving the elevation angle and orientation in different regions changes greatly, need look for star in the wide range search, it is less relatively to add that present star (prosperous promise (Sino) I broadcast communication satellite) is gone up emissive power, has also increased search and has looked for the star difficulty.Usually the satellite receiver orientation by the fixed-site/activity of reception, can be divided into fixed Satellite Receiving Station and mobile-satellite receiving station two big classes to star.Receive the fixed Satellite Receiving Station of fixed-site, it is that orientation and pitching by artificial adjustment receiving antenna reflecting surface realizes that star orientation (pitching and orientation adjustment) is sought in installation, not only Installation and Debugging are complicated, consuming time many, very effort, and one-step installation can not change receiving position behind the location, can not change the reception constellation on demand, both have a change, all need carry out complicated adjustment process again, so this kind search is looked for the star orientation method not to be suitable for moving and used and open-air the reception.And dynamic tracking is received star in moving process, promptly on mobile vehicle, follow the tracks of receiving satellite signal, need complicated tracking and stabilizing control system, make that the receiver price is higher, be difficult to enter family, therefore equally also be not suitable for fixedly receiving satellite signal of the open-air nothing of portable receiver.
The method and apparatus of Chinese patent 00810592.8 disclosed optimally orienting satellite dish.It discloses a satellite dish antenna, receive the method and apparatus of the signal of an above satellite, it receives in fact also is that a kind of non-moving fixed point receives, and and the unexposed star of how seeking fast, therefore equally yet inapplicable portable receiver field does not have receiving satellite signal regularly.
Summary of the invention
The objective of the invention is to overcome the deficiency of above-mentioned prior art, provide a kind of simple in structure, cost is low, and can be fit to carry open-air fixed point reception, can satisfy the fast quick satellite-searching method of the portable satellite receiver of seeking star fast again.
Another object of the present invention is to provide a kind of and be suitable for this method, and can effectively reduce the portable satellite receiver of invalid range and time to search.
The present invention's first purpose realizes, basic design is according to receiving the ground latitude and receiving constellation, preset receiving antenna reflecting surface orientation and luffing angle by manually tabling look-up, will with preset the orientation be the center ± 90 ° of spatial domains are divided into some fields of search, begin automatically by the setting order by presetting the orientation, adopt the spiral search mode, range searching locks orientation and pitching up to the signal maximum one by one.
Of the present invention can have dual mode automatically by the setting order, suppose ± 90 ° of spatial domains are divided into the odd number region of search greater than 1 field of search, then by prefabricated band of position spiral search earlier, after to both sides subregion spiral search; Suppose ± 90 ° of spatial domains are divided into the even numbers region of search spiral search greater than 2, then by a preset position left side or part district's spiral search on the right side.Said subregion spiral search can be by prefabricated position, and a side (90 °) volume-search coverage finishes, and forwards the opposite side volume-search coverage again to; The present invention reaches and seeks star fast for shortening search time as far as possible, and a kind of better is to adopt left and right sides great-jump-forward search, promptly from presumptive area, earlier to both sides neighbour's range searching, again to the search of both sides outer peripheral areas, the right search of jumping of a first from left.For example from presumptive area, to a side proximity search range searching, as do not find signal maximum, promptly jump to the search of opposite corresponding region rapidly, as finding signal maximum not yet, search is continued in next zone that goes back to former direction side again, as also not finding signal maximum, jump to the reverse direction correspondence again and do not receive the rope area searching, until finding signal maximum to end.The great-jump-forward search of this left and right sides helps by presetting definite position, and probability big near field in first both sides is searched for, and far field, both sides domain search is saved search time thereby reach again, does not waste the quick search of backhaul and seeks star.Because search is carried out for outwards adopting from the center in the shape of a spiral mode, so the receiving antenna reflecting surface changes pitching simultaneously and also changing in the orientation, thereby orientation, pitching are changed simultaneously.Seek in the star process if find signal maximum in search, then stop search automatically (as realizing) by comparator circuit.
The present invention adopts the spiral scan search, makes search earlier in the big central area search of probability, then outwards enlarges shape search in the shape of a spiral, also helps reducing and intercepts and captures search time.Have certain width because of receiving electromagnetic wave beam, spiral scan can be undertaken by a fixed step size, sweeps journey step length, covers overstockedly, though that scanning is missed is little, searches for required stroke and extends greatly, and search time is long; As sweep journey step and grow up, cover too smallly, probably cause scanning to miss, the sky that star can occur can not find is swept.For the spiral scan miss probability is minimized, according to the received signal requirement, by once intercepting and capturing criterion, design determines that the stroke cover width is 1/3 (a non-exact value) of received beam width in the spiral scan backhaul, determines to sweep Cheng Buchang with this.For example the received beam width is 5 °, sweeps Cheng Buchang (at interval) and then can be set at about 4.5 °, can both reach like this and effectively shorten sweep time, avoids occurring drain sweep again.
Search the star time for ease of further shortening, place restrictions on no efficient search to the dead space, portable satellite receiver of the present invention, a kind of better is at rotational orientation and pitching zone limit switch to be set all, thereby making receiving antenna reflecting surface orientation, pitch rotation search the star scope is limited in effective spatial domain, thereby avoid the no efficient search of antenna in invalid spatial domain, lose time.Said spacing setting, in China's territory scope, receive prosperous promise (Sino) I broadcast communication satellite, can be by orientation ± 90 ° and pitching+10 °～+ 80 ° settings (other countries area and/or receive other constellations, then determine search orientation, pitching scope) according to receiving territory and constellation.For helping presetting setting antenna reflective face orientation and/or pitching, make preset position as far as possible in the big central area of the probability of acceptance, for example compass and/or angle display device can be set on receiver, help that preset position is carried out coarse localization and preset.
Receiver of the present invention is for effectively overcoming accumulated error in the search procedure, also be provided with orientation, pitching crawl micromatic setting, promptly after the directed end of automatic star-seeking, can be by the crawl fine setting (as keyboard) that is provided with, realize at orientation and pitching both direction that crawl is little and move accurate adjustment, make the antenna reflective face received signal reach accurate maximal value (differentiating) as showing relatively by the signal on screen.
Consider some situation (as influences such as artificial collision, winds), finish receiving the back receiver slight displacement might take place, thereby the received signal maximal value is changed.The present invention also is provided with the memory storage circuit in control circuit, the maximum value position (orientation and pitching) that search is reached is stored in the memory storage circuit (or storer), when move in the receiver original place, received signal changes or track rejection, can directly the positional value extraction of storage be used, do not need to start anew again to search for, avoided search fully again to lose time, thereby saved release time greatly.
Pack up volume for effectively reducing, feedback type feed of the present invention and receiver adopt the split unitized construction, during use it are combined into integral body, pack up into its fractionation, can reduce to pack up volume greatly like this, make it more to help portable.
The fast quick satellite-searching method of portable satellite receiver of the present invention, preset reflecting surface orientation and pitching manually owing to adopt, initial search is set at seeks star probability center of maximum district, seek star and adopt outside spiral search mode again from the center, automatically range searching is sought star one by one, the quick method for searching star till receiving the signal maximum.Thereby make the portable satellite receiving trap, have " click-through " fast automatic star of seeking, both need not the tired multiple star of manually seeking, omitted the tracking and the stabilizing control system of automatic star-seeking complexity again, the cost price of receiver is descended greatly.Spiral search by the outside expanded search in center, and is covered as 1/3 of received beam width by stroke in the sweep retrace and determines to sweep Cheng Buchang, it is short, quick not only to have the journey of searching, and required time is short, helps seeking fast star, and do not have the generation of drain sweep phenomenon substantially, seek star accuracy rate height.Compass and/or angular display unit are set simultaneously, relatively accurately preset receiver reflectance face orientation and pitching, and orientation and pitching limit switch be set, search sweep is limited to effectively and limited orientation zone, significantly reduce useless scan sector scope, can reduce the hunting zone, also help improving and search accurate rate fast, reach and seek star fast.The inventive method and device have easy and simple to handlely, adopt the split unitized construction on automatic star-seeking " click-through ", the especially structure, and volume is little, and is in light weight, can be portable, portable, be specially adapted to portable satellite receiver.
Below in conjunction with an embodiment, further specify the present invention.
