Frequently Asked Questions
- How are results for a pass request shared? Results from your pass request are
shared via Dropbox. Once the results are ready, the contact email will be sent to
the link to access the results. - How long does it take to receive the results of a pass request? Results from a
pass request are sent to the contact emails address within 6 hours after the
booking time. - How long does it take to receive confirmation of a pass request? Submitted
pass request orders are checked before being accepted, this can take up to 1
hour after ordering. - Why do I need to book slots which are at least 30 minutes in the future? The
current MVP service requires a minimum of 30 minutes to process an order and
schedule it with a given ground station. It is possible to book slots less than 30
minutes into the future but they may be rejected or missed. - Why was my order rejected? If your email has been rejected, check the reservation email you received. Most likely a value was not submitted correctly or was missing.
- Error 403? If this error occurs, take the following steps:
- Refresh the page (Ctrl + F5)
- If this does not resolve the issue, close the tab and revisit the Dashboard after 4 hours.
- How to estimate SNR using baseband recording? Using your RF spectrum plot from the program SDR# of your recording, estimate the power of the signal and the noise floor. The SNR in dB is the dB difference between the peak signal and the noise floor.
- How to estimate the station misalignment? To find the estimated misalignment of the dish, sweep across a target signal while keeping either the elevation or azimuth constant. Using the baseband recording, note the rotor position once the signal reaches a minimum signal strength (SNR). Additionally, note the rotor position once the signal falls below this minimum SNR. Estimate the beam centre point (Azi/Ele) between these two recorded positions and compare it with the satellite’s calculated position. This method will give you an indication of any misalignment.
- Why are some azimuth values negative in my results log? The rotor has an operational range of -180 degrees to 540 degrees. In certain cases the azimuth angle may be displayed in the negative form. Add 360 degrees to negative values if necessary.
