Surveillance & Monitoring Symposium Melbourne (1989)


Another institution whom active in handling symposium on deformation besides the one organized by FIG is the Department of Surveying, U of Melbourne. They have organized an event "Surveillance & Monitoring Symposium - SAMS '89. The symposium was held at Melbourne University in November 1989.

Groten - Airborne Gravimetric Studies 1989


An early paper on airborne and satellite borne gravimetric studies was written by Erwin Groten way back in 1989. This is among the pioneer papers on airborne gravimery. Groten is with Institute of Physical Geodesy, TU Darmstadt. The paper among others discussed the principles of airborne and satellite borne recovery of the gravity field where the ideas of global gravity field determination based on spherical harmonics expansion.

Numerical solution of Molodensky problem – Sideris & Schwarz (1988)


During period 1987- 88 saw many research developments on gravity field reported by Calgary group. One of them is a paper “Advances in the numerical solution of the linear Molodensky problem” by MG Sideris and KP Schwarz published in Bulletin Geodesique 62:5-69 (now known as J of G).

OSU GS Geodynamic Program 1988


OSU Geodetic Survey is very active in geodynamics program. In 1988 a report "Basic research for geodynamics program (at OSU)" was prepared for NASA by GS Dept. Report by Ivan I Mueller covers activity from July 1, 1987 through June 30, 1988.

Among the activities covered were;

1. Earth Rotation Parameter Determination from Different Space Geodetic Systems
2. Utilization of Range-Difference Observations in Geodesy
3. An Algorithm for Crustal Deformation Analysis
4. Orbit Determination for the Global Positioning System of Satellites
5. Reference Frames for Geodynamics

Among the publications as research outcome were;

1. Further Considerations on Combining Earth Rotation Observations from Different Space Geodetic Systems, Bulletin Geodesique, 1988.
2. Baseline Estimation with Semidynamic and Geometric Satellite Methods, Bulletin Geodesique, 1988 or 1989.

UNB's paper at FIG 1988 Symposium


There were a number of papers by UNB SE group presented at 1988 Symposium. Among them were;

"Integration of the GPS with geodetic levelling surveys in ground subsidence studies"

"Integration of geotechnical and geodetic observations in the geometrical analysis of deformations at the Mactaquac generating station"

Deformation Symposium - Fredericton (1988)


Dept of SE UNB hosted the 5th FIG Symposium on Deformation Measurement held in Fredericton on June 1988. The organizing committee of the symposium was chaired by Prof Adam Chrzanowski.


 

The proceedings

I have made a wrong move not attending this symposium even though were there. I took leave instead and went home for summer break.

Pelajar PSM 2010/11


Pada sesi 2010/11 ada empat pelajar 4Sgu yang berminat untuk membuat PSM dengan tajuk mereka kesemuanya melibatkan least squares adjustment. Mereka ialah;
  1. Muhammad Izzudin bin Abdul Jalil - " Software development for EDM calibration computation with implementation of Variance Component Estimation method"
  2. Md Yusop bin Usak "The adjustment of precise levelling network with emphasis on the optimization of error modelling"
  3. Erlya Herlin bt Ngadimin "The adjustment of precise levelling network: Incorporating the post-analysis using Almost Unbiased Estimation technique".
  4. Abza bt Khalid "The modelling of correctivesurface for GPS height conversion in Klang Valley".
Abza mengerjakan projek tesisnya dalam satu semester saja (ie., semester 2) setelah menukar kepada tajuk baru kerana tak mahu meneruskan tajuk asalyang baerkaitan dengan smart watch heighting accuracy.
