[Mgsn-announce] New GS reference model, v 0.2.0

[James C. <jw...@st...>]

We've published a new informal ground station reference model,
http://mgsn.sourceforge.net/docs/modelv0.2.0.php.  It attempts to itemize
core ground station hardware and services.  These will then be captured in
GSML.  The online pages are derived from our recent IEEE Aerospace
Conference paper, Ground Station Markup Language.  It will be online at
http://swig.stanford.edu/public/projects/satellite/ once the final draft
is submitted.

We expect to be publishing draft GSML specification shortly.  This will be
derived directly from the above model.

We are seeking any feedback on the model.  What additional hardware is
needed?  Anything we missed?  Please be sure to read the paper as well.

Thank you.

[Mgsn-announce] CVS now holding 1.2.0

[James C. <jw...@st...>]

We've begun work on Mercury version 1.2.  Documentation pages are under
development to show what the work is on 1.2
(http://mgsn.sourceforge.net/docs.php).

The CVS repository now contains our latest code work on 1.2.  We're
actively working on the process manager and enabling Mercury to perform
fault detection and recovery.  Once we have this working, we'll release a
beta version.

Thanks.

[Mgsn-announce] Mercury 1.1.2a released

[James C. <jw...@st...>]

We have released the next version of Mercury, 1.1.2a.  It contains
numerous bug fixes from 1.1.1c.  Arhictecturally, it is the same as
1.1.1c.

Please report any bugs at
http://sourceforge.net/tracker/?group_id=64075&atid=506198.

Work is under way on 1.2.  We are improving process management and error
recovery.  Providing an "access server" for agent based interfaces to
Mercury scheduling and control.  And extending Mercury implementation of
the GSML session level.  These are just a few of the additions.

Thanks.

[Mgsn-announce] New Mercury web site

[James C. <jw...@st...>]

We're in the process of deploying a new Mercury website at 
http://mgsn.sourceforge.net/.  The goal is to have updated documentation 
on system architecture, design, and implementation.  Be sure to check out 
the latest news for documentation releases.

Also, we should be realeasing the next version of Mercury, 1.1.2, in the 
next week.  Mercury 1.2.0 is already well underway as we seek to put some 
fault tolerance and recovery components in the system.

Thanks.

[Mgsn-announce] Patched version of Predict

[James C. <jw...@st...>]

Hello,

I've released a patched version of the latest Predict release, 2.2.1.  
Mercury uses Predict to calculate antenna pointing angles and doppler 
effects for radio tuning.

The current version of Predict, 2.2.1, has a bug in the way it reads data 
from the socket.  This causes Predict to fail when using the "GET_DOPPLER" 
and "GET_SAT" commands via the socket interface to predict.

I've made the patched version of Predict available on Mercury's 
Sourceforge account at:

http://prdownloads.sourceforge.net/mgsn/predict-2.2.1p0.tar.gz?download

I've also notified the developers of Predict and they will be releasing it 
with the next version.

Thanks.

PS...We will be releasing mercury-1.1.2 by the end of next week with major 
bug fixes and updates.  Hopefully the documentation will be improved as 
well!
