Aloha GMAT Team,

I have updates for the problem that I have described in the previous post that 
might narrow down the root causes.

I have noticed that if I define a sensor in the editor and 

1. I declare it as an Imager, then all the source lines below Create Imager 
wfovImager; are deleted when I save the script from the GUI.
2. I declare it as an Antenna, then only the source line below Create Antenna 
wfovImager; is deleted when I save the script from the GUI.

Thank you and best regards,

BU

Subject: [Gmat-users] Question about Imager vs Antenna hardware resources

Aloha GMAT Team,

I am working on the (re)design Active Debris Removal in GMAT. I have described 
the ADR mission, designed with STK, in 

Udrea, B. and M. Nayak. A Cooperative Multi-Satellite Mission for Controlled 
Active Debris Removal from Low Earth Orbit. in 2015 IEEE Aerospace Conference. 
2015. Big Sky, MT.

I am displaying the relative trajectory between a Servicer Space Vehicle (SSV) 
and the Client Space Vehicle (CSV) in the CSV LVLH reference frame in the Open 
Framework Interface (OFI) viewer. I have set up a script to display the mask of 
an imaging sensor on the servicer in the OFI viewer as well. 

I believe I have found an inconsistency between Imager and Antenna resources. 
If I declare the imaging sensor as an Imager, it is displayed the Hardware 
branch of the Resource tree. The result of Show Script is:

%----------------------------------------
%---------- Hardware Components
%----------------------------------------

% BUG? 
% Wide Field of View (WFoV) imager should be declared % as an Antenna instead 
of Imager to avoid an % inconsistency between the GUI and script modes % Create 
Antenna wfovImager; Create Imager wfovImager;

However, if I declare the imaging sensor as an Antenna, it doesn't show up in 
the Hardware branch. This is consistent with the Ex_R2020_OF_FielfOfView.script 
from \samples.

I have observed the following: if I modify the script from the GUI with the 
imaging sensor declared as an Imager, change the script from the GMAT GUI, and 
save, the script lines that define the Direction, SecondDirection, and 
HWOriginInBCS of the wfovImager are not written to the script. If I declare the 
imaging sensor as an Antenna and change the script from the GUI, the wfovImager 
lines are written to the script.

As I am new to GMAT and the GUI-script duality I am not sure this is desired 
behavior or an inconsistency.

Can you please help me?

Regards,

Bogdan
