Measuring launch and motion parameters

A system for monitoring launch parameters, comprising:

• an apparatus, including:
• a transmitter optical subassembly including at least one laser source configured to transmit a sheet of light such that a flying object passes through the sheet of light along an expected flight path of the flying object;
• a receiver optical subassembly configured to receive light transmitted by the transmitter and reflected back from the flying object as the flying object passes through the sheet of light, wherein at least one preliminary launch parameter of the flying object is determined based on the light reflected back from the flying object;
• at least one camera subassembly comprising a camera having a field of view, the camera subassembly configured to take a plurality of pictures of the flying object in response to a triggering event that is based on the at least one preliminary launch parameter, and the plurality of pictures of the lying object are taken in a relevant area within the field of view that is determined based on the at least one preliminary launch parameter;
• a mobile device configured to process the plurality of pictures captured by the at least one camera and calculate at least one non-preliminary launch parameter;
• and
• a backend server configured to receive and store the at least one exact launch parameter.

A method for monitoring launch parameters, comprising:

• transmitting at least two laser sheets sequentially such that a flying object passes through the at least two laser sheets along an expected flight path of the flying object, wherein the at least two laser sheets are not parallel;
• receiving light reflected from the flying object as the flying object passes though the at least two laser sheets, using a receiving subassembly comprising at least one photodetector module, wherein at least one preliminary launch parameter of the flying object is determined based on the light reflected back from the flying object;
• tuning a camera having a field of view, within at least one camera subassembly, the camera subassembly configured to take plurality of pictures of the flying object in response to a triggering event that is based on the at least one preliminary launch parameter, and the plurality of pictures of the lying object are taken in a relevant area within the field of view that is determined based on the at least one preliminary launch parameter;
• determining ratios of the time interval to estimate a velocity, an elevation angle and an azimuth of the flying object;
• analyzing a curve of an intensity time plot based on the light reflected by the flying object;
• determining if the curve of the intensity time plot corresponding to the light reflected from the flying object matches a shape of the flying object;
• and
• estimating a velocity of the flying object based on a correlation of the intensity time plot and a known shape and size of the flying object.
