Abstract:Summary As regards the concept of complete weight p with which an observed quantity (e.g., the direction of theA–G net) should enter the net adjustment, according to Eq.(1), apart from the fundamental weight p 0 ), determined by the number of repetitions, it should also contain the time parameter pt according to Eq.(11), where c>1 is a constant, and t is the number of days of observation, and also the refraction factor pr according to Eqs(17, 18), where q is the structural weight of the direction. The condition for being able to determine pr with the directions is observation by means of the three-directional vertex method2], because it is not possible to localize lateral refraction by angular methods. The theory of complete weight is in favour of observations with a high fundamental weight p 0 which automatically yield higher values of t, and also of pt. The introduction of the complete weight into the experimental directional net in Fig. 2 caused the mean value of the uneliminated refraction error to decrease from 0.24Prime to 0.12Prime, the mean square error of the adjusted direction being 0.17Prime. The value of the constant c was investigated and the method of determining the parameter pr was derived also for lengths measured electro-optically. Mention is made of the effect of complete weights on the length adjustment of a net in6].
