The proceedings content was focused on the following topics;

• Global Plate Motions
• Instrumentation and Modelling
• Regional Dynamics
• Modelling of Deformation
• Deformation Studies by GPS
• Horizontal Crustal Movements
• Vertical Crustal Movements
• Gravimetry and Crustal Deformation

Among the papers presented were the development of several recent global plate models using Lageos and other geodetic observations;

IAG Symposia - Ediburgh 1989

In August 1989 IAG celebrated its 125^th anniversary. To commemorate the event a series of IAG Symposia was held in Edinburgh, Scotland hosted by University of Edinburgh. This General Meeting later was re-named as Scientific Assembly. The first assembly was held in Tokyo (1982) and 1989 Edinburgh Meeting was the second. There were five symposiums held at Edinburgh meeting with theme as follows;

Symp 101 Global and Regional Geodynamics
Symp 102 GPS and other Radio Tracking Systems
Symp 103 Gravity, Gradiometry and Gravimetry
Symp 104 Sea Surface Topography
Symp 105 Earth Rotation

The meeting and symposia was held at Appleton Tower U of Edinburgh. What is so special about Appleton Tower? The Tower was named in posthumous honour of physicist Sir Edward Appleton (1892-1965). He was the Principal who oversaw the development from vision into concrete reality of the 1960s Edinburgh University buildings around George Square. Appleton won the Nobel Prize in Physics in 1947 for his seminal work proving the existence of the ionosphere during experiments carried out in 1924.

Sejarah Syarikat Peralatan Ukur Kern

 

Selain syarikat Wild ada sebuah lagi syarikat yang amat sinonim sebagai pengeluar peralatan ukur iaitu Kern. Kedua-dua syarikat pengeluar ini berpengkalan di Switzerland. 

Berikut adalah beberapa catatan ringkas tentang sejarah syarikat Kern. Kesemua info dipetik dari sumber berikut (link - kern milestones):

1819: Founding of Mechanische Werkstattle "Jakob Kern" Aarau, Switzerland. The first items produced were drawing instruments. 

1835: Later, he became well known for his geodetic and astronomical instruments including the theodolite which was purchased in 1835 for the well known General Dufour, who made the first triangulation survey in  Switzerland.

Theodolite produced by Kern in 1835 

1857: The two sons of Jacob join the firm - Adolf Kern-Saxer and Emil Kern-Rychner.

1857: new location - Zieigel, Aarau

1863: Jacob Kern retired from business

1885: Adolf Kern retired from the business and his son Heinrich Kern (1857-1934) assumed management responsibility for the firm.

1887: Emil Kern retired from business
