進一(yi)步地,所述衛星導(dao)航信(xin)號模擬器(qi)與(yu)上位機之(zhi)間還設置有(you)GNSS接收機,以避免衛星導(dao)航信(xin)號模擬器(qi)與(yu)載體(ti)導(dao)航控制器(qi)的衰減不一(yi)致(zhi)的問(wen)題,檢(jian)測結果可靠性更高(gao)。
具體(ti)地,載(zai)體(ti)導航控制器通過串口或網口與上位機連(lian)接(jie)。
以上(shang)本(ben)發明實(shi)施例所述的(de)(de)(de)(de)測試方法均(jun)適(shi)于(yu)帶有中國、美國GPS、歐洲Galileo、俄羅斯GlONASS中任一(yi)種(zhong)衛星(xing)(xing)導(dao)(dao)(dao)(dao)航(hang)(hang)(hang)系統的(de)(de)(de)(de)載(zai)(zai)(zai)體(ti),即衛星(xing)(xing)導(dao)(dao)(dao)(dao)航(hang)(hang)(hang)信號(hao)模擬器(qi)可(ke)以生成BDS、GPS、GLONASS、GALILEO、QZSS和GAGAN中的(de)(de)(de)(de)至(zhi)少任意(yi)一(yi)種(zhong)仿真衛星(xing)(xing)導(dao)(dao)(dao)(dao)航(hang)(hang)(hang)信號(hao),提供一(yi)種(zhong)兼容性的(de)(de)(de)(de)衛星(xing)(xing)導(dao)(dao)(dao)(dao)航(hang)(hang)(hang)模擬信號(hao)以適(shi)于(yu)不(bu)同衛星(xing)(xing)導(dao)(dao)(dao)(dao)航(hang)(hang)(hang)載(zai)(zai)(zai)體(ti)的(de)(de)(de)(de)導(dao)(dao)(dao)(dao)航(hang)(hang)(hang)控制器(qi)。進一(yi)步地,在其他實(shi)施例中,衛星(xing)(xing)導(dao)(dao)(dao)(dao)航(hang)(hang)(hang)載(zai)(zai)(zai)體(ti)軌跡仿真參數配置單元包括(kuo)車載(zai)(zai)(zai)、艦(jian)船、飛機和導(dao)(dao)(dao)(dao)彈中至(zhi)少一(yi)個運動模型,也就是說導(dao)(dao)(dao)(dao)航(hang)(hang)(hang)載(zai)(zai)(zai)體(ti)可(ke)以為帶衛星(xing)(xing)導(dao)(dao)(dao)(dao)航(hang)(hang)(hang)系統的(de)(de)(de)(de)無(wu)(wu)人(ren)機、無(wu)(wu)人(ren)汽車、無(wu)(wu)人(ren)艦(jian)船,甚至(zhi)是導(dao)(dao)(dao)(dao)彈等(deng),載(zai)(zai)(zai)體(ti)導(dao)(dao)(dao)(dao)航(hang)(hang)(hang)控制器(qi)的(de)(de)(de)(de)先行(xing)測試對于(yu)導(dao)(dao)(dao)(dao)彈研制的(de)(de)(de)(de)重要性就更(geng)為突出。
