Flight Status – What the last major event was. Typically it will be “Landed”, but it may be
something else if there was an anomaly in your flight.
Apogee – What the apogee of your flight was, and the time-to-apogee from launch detect (LD).
(About the elapsed times: To detect start-of-flight, the Proton uses the first reading above the Accel
Launch Detect G's threshold, before the LDA has been reached. While it’s technically possible that
this figure may be a little off, our experience has shown that it’s only off by one or two samples at
most… typically under 100 ms.)
Max Velocity – The maximum velocity that was reached, and the time from LD. This data comes
from the accelerometer, so it is very accurate, and not affected by the rocket's tilt angle or wind, etc.
Max Acceleration – The maximum acceleration that was reached in flight, in G's. With one motor
it will probably be within a few seconds of the Start of Flight, if you have a multiple stage or
airstarted motor system then it may occur somewhat later.
LD Alt – The actual altitude that exceeded the programmed launch detect settings, and the time from
LD. If the altitude is less than the programmed LDA altitude, you can assume that LD was due to
the accelerometer settings.
Low V Alt – The altitude at which deployments were enabled, i.e. the rocket slowed under 100
ft/sec for at least one second, and the time from LD.
Nose Over Alt – The altitude at which the rocket nosed over, typically one second past apogee, and
the time from LD.
For each enabled channel...
Channel Mode – The selected mode of the channel.
Channel Time – The time from Start of Flight that the channel was fired OR would have fired
if not inhibited
Channel Alt – The altitude at which the channel was fired OR would have fired if not inhibited.
Status Flags – Various flags that show any issues that were encountered that would inhibit the
firing of the channel.
Flight Time – The elapsed time from LD until landing detect, which is when the rocket drops below
30’ AGL for 5 seconds.
ASL Alt – The Above-Sea-Level reading of your launch site.
Temp – The temperature in Farhenheit at the time of launch. This will be very accurate if the Proton
has been powered on for 10-15 minutes, but will tend to be on the low side if you fly shortly after
powering up.
