# Function Description
• Vehicle yaw rate – Designates the change in vehicle
heading angle compared to the previous heading angle
received from GPS receiver, whenever GPS data is
available and accurate.
5 Time management The Cipia-FS10 OS maintains accurate “system time” in
GMT based on available clock sources like the cellular
network and/or GPS.
If neither of the two exist or are
‘up to date’, the Cipia-
FS10 device manages accurate time (using the internal
real-time clock) with a maximum deviation of 86 seconds
per 24 hours (0.1%).
6 Location
management The Cipia-FS10 main application updates the accurate
location register (RAM) at least every 1 second throughout
the entire trip.
The first location in a new trip is logged only after an
accurate FIX is acquired by the system GNSS.
The location register is not updated if the FIX quality
parameter is not higher than the programmed threshold.
Every new location record is registered along with its <fix
quality parameter>, <location acquisition time>, <speed
(m/sec)> and <heading angle>
Whenever the location register is not updated for longer
than the TH configuration parameter, the Cipia-FS10
device generates
a “GPS loss” event.
7 Video capturing
and upload The Cipia-FS10 application manages two video cyclic
buffers, for each connected camera (DMS & ADAS-
optional), if enabled in configuration (See
‘ ContRecording ’’
parameter):
• Event video buffer in RAM, intended to save a few
seconds of video before and after the occurrence of a
safety event.
• Global cyclic buffer in SD card, intended to allow
retrieval of video footage upon request from mobile app
or server.
Video in the global cyclic buffer is compressed using H.264
codec which can be used also by the FMS to play the
video.
The event video buffer from RAM is captured and saved
into NVM when the event occurs and according to
configuration file settings.
It is possible to instruct the Cipia-FS10 device to start
recording NOW a footage with a certain length, on
receiving such a command from the server. The captured
video includes
the “pre - buffer” that was in RAM at the time
the command was received.
The Cipia-FS10 device supports uploading of video footage
from the global cyclic buffer, according to the time frame
