Hi
I mentioned in an earlier email today that I'm doing a Sat 101 lecture for a ham club.
Just putting the finishing touches on the presentation, and I have a question....
I'm displaying a picture of AO-13 (my first sat QSO was on that bird) to contrast it with a picture of the the cubesats of today
The only dimensions I'm finding for AO-13 are 600 x 40 x 200 mm...this seems awfully small for a 92 Kg (plus another 30Kg for fuel) weight. (23.6 inches x 1.6 inches x 7.8 inches).
Were these dimensions actually in centimeters. and not millimeters?
Thanks
Philip N4HF
I can't find the precise dimensions. but here's a photo of the satellite structure being worked on:

That is definitely larger than 600mm (~23 inches) in the largest dimension) and more than 40mm in the smallest one, so I'm guessing that "mm" is a misprint in the only source I'm finding - http://www.om3ktr.sk/druzice/ao13.html - and should actually be "cm".
Thanks Paul

Well, "cm" doesn't seem right either. 600 cm is nearly 20 feet, as WB4APR just emailed to me (thanks Bob)
Getting the correct dimensions is not a big deal...as I said, just using a pic of AO-13 to contrast with that of a cubesat
Thanks for the help

Looking at the one picture the 600 millimeters looks close. Joe WB9SBD Sig The Original Rolling Ball Clock Idle Tyme Idle-Tyme.com http://www.idle-tyme.com On 6/4/2017 10:09 AM, Philip Jenkins wrote:

The misprint is that the 40mm should be 400mm and then the others can make sense. And the 200mm must be the width of a side.

There is a dimension scale at the bottom.

It's cool that the satellite had its own motor. Was it used much?

The motor was used to raise the perigee and change the satellite's inclination. It only carried enough fuel to reach the intended orbit.
The satellite was launched into a geostationary transfer orbit with a perigee of 240 km and an inclination of just a few degrees. The motor allowed the perigee to be raised to 1100 km and the inclination raised to 58 degrees.
