7 Vertical Angles and Precision Point Timing Calculation
7.1 Channel Number and Vertical Angle
RS-Helios-1615 has a vertical field of view from -16°to +15°. The minimal angular resolution is 1°.
The 32 laser heads are also called 32 channels. The laser channels and their designated vertical
angles are as shown below.

7.2 Exact Point Timing Calculation
The time required to complete one round of firing and recharging of 32 lasers is 55.56us. In each
MSOP Packet, there are 12 data blocks, and each data block stores measurements of 1 firing
sequences of 32 lasers, therefore, each MSOP Packet records 12 firing sequences of 32 lasers. It
takes 55.56us to complete one round of firing and recharging of the 32 lasers. RS-Helios-1615 has
included the anti-interference feature, therefore the firing sequence of the 32 lasers is irregular.
The exact point timing of different lasers in single return mode and dual return mode can be
calculated according to the time offsets listed in the tables below:
