By measuring the time this takes, the height of the ice beneath the spacecraft can be calculated.
The diel variable was obtained by measuring the time difference between the encounter and the previous sunset.
It works like radar, calculating distance by measuring the time it takes for a reflected signal to return.
The distance to the meteor can be determined by measuring the time lapse between the transmitted and reflected radar signals.
By measuring the time between the outgoing and returning pulses, it was possible to estimate the height and number of layers.
The range to a target is determined by measuring the time that a radar signal takes to travel out to the target and back.
At a high level, our technology operates by measuring the time it takes the signal to travel from the wireless sticker to an access point.
Various microfluidic approaches have been devised to mimic traversal in vitro by measuring the time required for cells to pass through a constriction.
The penetrant's transport across PVA films were monitored by measuring the time evolutions of through thickness fluorescence intensity profiles.
By measuring the time taken for the radar echo to come back, the distance can be calculated, since radio waves travel at the speed of light.
Because the light bursts are so short, the system can gauge how far they've traveled by measuring the time it takes them to reach the detector.
