What is PPS synchronization?
Pulse per second (PPS) is the simplest form of synchronization. PPS is a signal that outputs a high logic level once a second. The device interprets every subsequent pulse as occurring one second after the previous pulse.
What PPS means?
Post post scriptum
Post post scriptum, an initialism written as a footnote to a p.s. footnote. P.P.S. is defined as an additional comment or “postscript” which is added to a letter. An example of P.P.S. is when a girl adds “P.S.: I love you.” and then adds “P.P.S.: I miss you.” on the bottom of a letter.

What does PPS mean in banking?
Positive Payment System
The concept of Positive Payment System (PPS) involves a process of reconfirming key details of large value cheques to the Drawee Bank before presentation of the cheques.
How is the lidar data collected and processed?
The point data is post-processed after the lidar data collection survey into highly accurate georeferenced x,y,z coordinates by analyzing the laser time range, laser scan angle, GPS position, and INS information.
How does the INS system work with lidar?
An INS system measures roll, pitch, and heading of the lidar system. Lidar is an active optical sensor that transmits laser beams toward a target while moving through specific survey routes. The reflection of the laser from the target is detected and analyzed by receivers in the lidar sensor.
How does a laser pulse return to a LIDAR sensor?
One emitted laser pulse can return to the lidar sensor as one or many returns. Any emitted laser pulse that encounters multiple reflection surfaces as it travels toward the ground is split into as many returns as there are reflective surfaces.
What is the absolute height of a LIDAR?
Typically, lidar-derived elevations have absolute accuracies of about 6 to 12 inches (15 to 30 centimeters) for older data and 4 to 8 inches (10 to 20 centimeters) for more recent data; relative accuracies (e.g., heights of roofs, hills, banks, and dunes) are even better.
