magicGNSS now processes GPS+GLONASS observations for RINEX files containing measurements from both systems. For a GPS-only or GLONASS-only processing, please submit your RINEX files directly to: http://magicgnss.gmv.com/ppp.

GAPS is temporarily not processing data sets in "Kinematic" mode.

magicGNSS now estimates piecewise linear tropospheric zenith delays (TZD) rather than piecewise constant TZDs.
The report provided by the PPP Software Centre has been updated with the date of processing and other minor changes.

2009/11/20
In "Kinematic" mode, the tropospheric zenith delay, gradients and receiver clock values included in APPS' '.sum' file were erroneous. This issue has been fixed.

2009/11/13
The process noise applied to the tropospheric zenith delay parameter in GAPS has been adjusted.

2009/11/04
The following changes have been made to GAPS:

• Until now, all "Kinematic" requests were actually processed in "Static" mode by GAPS. This issue has been fixed.
• gzip compression ('.gz') is now accepted.
• A bug has been fixed in the computation of the latitude, longitude and height standard deviations.

2009/10/22
The height discrepancy sometimes reported in APPS' results has been fixed.
