“…In order to find the frequency peak f 120 generated by 120°symmetry of the AJISAI RRA (Otsubo et al, 1999) we were investigating a spectral range from 0 to 2.5 Hz with 20 lHz step. Because of the 120°signal, the true frequency of the body is 3 times smaller: f apparent = f 120 /3.…”

“…The total number of ob- As to the average RMS value: it is about 25 mm for the both satellites Stella, and Starlette, respectively, as computed for the year 1996 and about 12 mm and 11 mm for the same satellites in 2000. It can be also noticed that the accuracy of the measurements for the satellite Ajisai is worse than the accuracy of the measurements of the satellites Starlette or Stella, this is referred to the so-called satellite signature (Appleby 1992;Otsubo et al 1999).…”

The satellites laser ranging from Helwan SLR station during the last 20 years are discussed. The internal calibration method used at the Helwan SLR station is explained. The root mean square value of the calibrations carried out during the period from 1991 to 2008 is computed. To clarify the difference in the accuracy of the measurements, the results of the analysis of the data taken for all the satellites after the upgrading (2000) are given and compared with those of the satellites observed before the upgrading (1996). The total number of passes of the satellite observed during the period from 1991 to 2008 is presented and the results are compared with the other SLR stations.

“…For all laser ranging satellites the array of corner-cubes, which reflect the transmitted laser signal back to the tracking station, is displaced from the center-of-mass of the spacecraft (Otsubo et al, 1999). Furthermore, the orbit determination is referred to this reference point and so the observed ranges must be corrected accordingly.…”

The paper concerns on the satellite laser ranging (SLR) in Egypt. The three generations which can be loosely defined by their single shot root mean square precision, are discussed. The laser generators used at the Helwan half automatic and full automatic stations are described. The equipments used for the operation of the satellite laser ranging and their upgrading are presented. The observations carried out from Helwan-SLR stations are mentioned. The importance of the satellite laser ranging from Egypt and their contributions to the SLR network are explained. The modification requested for increasing the performance of the Helwan-SLR station is given. ª 2015 Production and hosting by Elsevier B.V. on behalf
