[MOIMS-NAV-EXEC] FW: Proposed Draft Orbit Hybrid Message (OHM)

[Berry, David S (3920)]

All:

Attached is Dan Oltrogge's work on the ODM revisions for your review and comment.  If you have a chance to take a look prior to the meetings that start 23-March-2015 that would be great.

David

P.S.:  More to come!!!

Subject: Proposed Draft Orbit Hybrid Message (OHM)

All –

>From our last NAV WG meeting in London, I was tasked with scoping out an Orbit Hybrid Message (OHM) to augment the existing Orbit Data Message (ODM) types (OMM, OPM and OEM).

For your consideration and as promised (and even on time!), a proposed draft of this new message type is attached.  To save you some time, most of the relevant OHM content is contained in Section 6, with additional verbiage in the earlier sections and in Section 7 and in the appendices.

As a reminder, the principal drivers for the new message are:

(1)    Additional use cases:

a.       Satellite operators needing a succinct message type to contain covariance, ephemeris and/or orbital states, maneuver info

b.      Small satellite (e.g. CubeSat or “sprites” mission) en masse deployments containing between 50 and 200 objects per deployment;

c.       Space tracking agencies (e.g. STRATCOM, ESA, JSpOC, ISON, ComSpOC, etc) needing to share large quantities of orbital ephemeris and satellite physical characteristics info for as many as 200,000 objects as much as three times per day.

(2)    Need to make the messages smaller by:

a.       Allowing more optional data within a standardized set of options, so that the user only has to share the information which the user will ultimately need;

b.      Combining the requisite features of multiple message types (OMM, OPM and OEM) into a single message to eliminate duplicative message header information.

I want to thank Dave Finkleman and Doug Cather and several SDA operators for their willingness to review and provide suggestions on the message and to Dave Vallado and Sal Alfano for working with me to develop overall message content.

I look forward to discussing this new proposed message format and content with you.  We can discuss in detail at the upcoming meetings in Pasadena as well.

Thanks,

Dan
