exponentially averaged to improve precision and facilitate
reading. (HDG, STW, AWA, AWS, TWA, TWS, TWD, COG, SOG,
Depth ...)
- Optional extension with atmospheric pressure, cabin
temperature and relative humidity transducers. The
ATM200 model is originally equipped with a 9-axis
gyrocompass with autocalibration, internal GPS and
meteorological sensors.

Output data Filtering:
Unlike other existing gateways on the market, the
ATM105A1N / 2/3 and ATM200 establish a rotating output
sequence that is optimal to avoid both overflow and to
ensure that all data is sent in a short space of time. time over
slow NMEA0183 channels. (no more than 1 sec).
These Ocenav gateways limit the frequency of repetitive
type sentences (Heading or COG / SOG, for example)
received from NMEA2000 between 1 and 4 per second
depending on their priority, since it is a very fast bus
(250,000 bps).
There is no such limitation for security sentences (AIS /
Marpa).
Each channel has its data output filtered with its
corresponding input, eliminating redundancy. In this way,
the data traffic is reduced to the minimum possible, because
only those that are not available on that channel are sent. In
addition, dangerous data loops are eliminated.
