New GNSS will cause a synergetic effect and not chaos
Sergey Revnivykh
We do not see any conflict among GLONASS, GPS and Galileo, COMPASS.
All compatibility issues shall be resolved within ITU coordination procedure.
On the contrary, as I have already emphasized, we see that in future these
GNSS will complement each other for the benefit of users  [more]
Solving the GPS gap
Antonio Angrisano, Armando Pacifico, Mario Vultaggio
The current GPS civil service provides suitable performance only in situations of good electromagnetic visibility; the positioning becomes difficult in severely signal degraded environments, e.g. mountainous or urban areas. The GPS gaps can be partially solved employing spacebased augmentations [more]

VLBI geodetic precision with different models
Erhu WEI, Jingnan LIU, Peijing PAN
The article introduces several common ocean tide models and computes the global VLBI data during 2001-2007 using the OCCAM 5.0 software platform. It compares and analyzes the precision of geodetic parameter’s result using these models, and gives us the best ocean tide and nutation model combination. [more]
