This includes a map of the World Stations in September 1999; Station Position Modelling and Reference Frame; Estimated Parameters; a diagram showing Apriori Constraints to SINEX data through New Apriori Constraints.
  
• Title: SLR GLONASS Orbit Determination [PDF_325k]
  Forum: IGEX-98 Workshop
  Location: Nashville, Tennessee
  Date: 13 - 14 September, 1999
  Author: Ramesh Govind, John Dawson & Geoff Luton
  Summary: The intense observation campaign during IGEX-98 provided a data set that was used to compare and calibrate SLR and microwave determined GLONASS satellite orbits. Orbit determination of the GLONASS satellites were undertaken using the SLR data observed from November 1998 to March 1999. The resulting trajectories generated from this estimation process are compared to those produced by the Centre for Orbit Determination in Europe (CODE) IGS Analysis Centre using the microwave data. The results of these comparisons are presented and conclusions given in the form of differences in the satellite trajectories (radial, along and cross track) and a set of transformation parameters between these two orbit types. The precision of the estimated set of station coordinates (SSC) -- over the five monthly solutions -- is given in the form of their repeatability. The estimated SSC are compared to the ITRF97.
  
• Title: High Precision Determination of Station Heights of the Keystone Satellite Laser Ranging Network: Developing Optimum Observation Requirements [PDF_280k]
  Forum: Journal of the Telecommunications Advancement Organisation of Japan
  Location: N/A
  Date: 1998
  Author: Ramesh Govind
  Summary: The KSP network, comprising the co-location of VLBI, SLR and GPS space geodetic techniques, was established in 1996 by the Communications Research Laboratory (CRL) to monitor regional crustal deformation in the Tokyo metropolitan area. The pre-requisite for the scientific objectives and outcomes of the KSP network to monitor any pre-cursory / pre-seismic crustal movement is the ability to determine tracking station positions at a precision and accuracy of one mm, or better using a very short time span of observations; one week to one month. The rationale for the study, therefore, was to establish an "observation budget" and develop computation strategies for the Keystone SLR network that would meet the geodetic precision requirements of the specifications. Several factors limit the size of the observed data that is produced by any given SLR station. For the purposes of the study, observation scenarios were adopted which were both realistic and matched well with the output of some of the most productive SLR stations currently operating in the world. Several computation procedures were employed comprising single and multiple satellite solutions, with varying arc lengths, of Lageos-1, Lageos-2, Ajisai and Etalon-2.
