Revision of Survey Results of Control Points
Atsushi YAMAGIWA and Yohei HIYAMA
Following the Tohoku Earthquake, notable crustal deformation occurred over a wide area of eastern Japan, which led to the halt in the publication of Survey Results of GEONET stations, triangulation stations and Survey Results of bench marks in the affected area. The revision of the Survey Results of bench marks was, in essence, achieved through resurvey. Leveling was conducted and network adjustment was calculated based on the revised elevation for the Origin of the Japanese Vertical Control Network...

QZSS LEX message data for Precise Point Positioning
C H Wickramasinghe and L Samarakoon
It’s demonstrated through the research that IGS Ultra Rapid SV ephemeris and clock corrections are accurate compared to LEX data, thus for best real time positioning, the IGS Ultra Rapid data is the...

Mitigating the systematic errors of e-GPS leveling
Lao-Sheng Lin
The test results show that the proposed method can mitigate the systematic errors of orthometric height H from e-GPS leveling efficiently. We present here the first part of the paper...

EGNOS + Galileo = safer skies
Europe’s two satellite navigation systems could combine in future for heightened performance, an airborne test has confirmed. A helicopter flight took place above an Alpine valley, the one place on Earth where Galileo services are already routinely available. Results of last autumn’s flight test show that adding Galileo signals to the European Geostationary Navigation Overlay Service – EGNOS – that currently augments the accuracy and reliability of US GPS signals over Europe should boost its accuracy significantly. Operational horizontal and vertical distance ‘protection levels’ for safety were cut by approximately half by combining use of GPS and Galileo within EGNOS...[more]
