What kind of instruments are currently used, when ground control is monitoring a docking of new ship (or) segment to the ISS.

Do they monitor it at all?

  • $\begingroup$ In Mission Control (MCC-H and MCC-M) a bunch of workstations display ranges, attitudes, angles, velocities and other data. Mission control specialists use their eyes and brains. $\endgroup$ Aug 5, 2013 at 9:14

    $\begingroup$ There are multiple translated and commented videos of docking on youtube (such as this one youtube.com/watch?v=oRGl7MZJVno video of Soyuz TMA-06M automated docking using Kurs working in TORU mode). $\endgroup$

    $\begingroup$ Ah, yes, thank you, that's a leftover, Soyuz TMA-06M was going in automated mode. Initially I wanted to post this youtube.com/watch?v=aLbJqjASD60 video of Progress M-01M going in TORU mode, but then decided to go with Soyuz TMA-06M as a bit more spectacular and with enough suspense. $\endgroup$

    $\begingroup$ Of course they monitor the whole progress. It's their mission. Isn't it? For instance, take Soyuz. There's a camera on both ISS and Soyuz (filming each other) providing live telecast of what's happening out there. BTW, what do you mean by "instruments". IMO, Ground control uses a lot of computers ;-) $\endgroup$ Aug 6, 2013 at 0:47

YES it is monitored by ground control station but it is controlled by the astronaut in ISS or sometimes it may be automated

space vision system which uses camera to capture 2D images and then convert it to 3D images by using computer . And with the help of this system astronaut uses the robotic arm . but this system has certain problem

TRIdar is a relative navigation vision system which uses a 3D camera and thermal imaging (LASER based)

This laser- based system tracks retro reflectors located on the ISS to provide bearing, range and closing rate information. While reliable, target based systems have operational limitations as targets must be installed on target payloads. This is not always practical or even possible. For example, servicing existing satellites that don’t have reflectors installed would require a targetless tracking capability.


TORU has two joysticks which can be used to manually fly the ship.The left joystick is used to control the movement of the ship and the right joystick is used to control its orientation. The system also includes a camera that is mounted on the docking spacecraft and provides visual feedback when the spacecraft is remotely controlled from the station to that it is docking. TORU also transfers sounds from the spacecraft that may provide indirect information about the docking process

kurs docking system it is used in ISS and MIR when a vehicle approach the space station it will emit radar pulses from multiple antennas and change in the strength between the antennas allows the system to compute relative position, attitude, and approach rate.
