摘要
1990年4月和7月分别在公路上用三台WM102接收机进行试验。初步认为:车辆频繁从天线附近通过所产生的影响对观测是不利的。因此,GPS测站应尽量远离交通量大的路边;观测前,接收机振荡器应有足够的通电预热、测站静置时间。
Three WM 102 receivers were used to conduct an experiment on highway in April and July, 1990, from that the preliminary conclusion is: the observati on was affected by the frequently transportation, and thus, GPS survey station should be as far as(?) could be away from heavy-traffic roadside and before observation start, rec(?)ivers' oscillators should have enough time for electrifing, pre-heating and station stilling.
