OpenCPN for A20

We continue with yachts automation. For our device A20 , we make a package OpenCPN.

OpenCPN User Manual with pictures can be found here. Possible use that device by VNC Viewer with Android SmartPhone.

Right on our device you can placed detailed sea maps for all navigable waters.

This Chart-Plotter-Navigator for Yacht with the ability to connect the AIS. For this device, there plugin, which works with low-cost receiver to be connected to the antenna VHF.

NodeRed and zyGrib apps

For our new customers, we have adapted our device a20 for the yacht. Now, it can not only manage multiple switch devices like ESP8266-EVB-BOX through the MQTT server, 

but also to download weather broadcast and predict marine weather around the world for 3 days ahead. 

MQTT – server

We launched MQTT server for our customers in Germany.

The picture of our demonstration unit, which operates as a directly to unit (20-35m),  through a local WiFi internet and via global networks without changing the settings of the home routers, thanks to our new server MQTT.

We recommend the following management application:

MyMQTT and MQTT Client

The our MQTT server is available only for our customers.

Physical simulation

I’ll try to explain the idea in more detail: Possible use equations on simplicial meshes is developed based on discrete exterior calculus (DEC). It is use discretization on simplicial complexes such as triangle and tetrahedral meshes. Method is the use of an algebraic discretization of the contraction operator and a combinatorial discretization of the wedge product. Also develop a discretization for spatially dependent Hodge star that varies with the permeability of the medium. Equations of any physical process automatically are first rewritten using the exterior calculus notation. We change differential operators by the exterior derivative, Hodge star and wedge product operators. Discrete operators based on the python framework.

As a result, our calculations are reduced to the multiplication cycle of our data into two-three the matrices are calculated for each time point. Each element of the matrix connected to the finite element of the object (part of engine). The key point is that all steps are automated and the algorithm calculates and physical fields too.

The center of mass can be regarded as a dipole field. Enter additional space for this point of the center of mass. And to build additional space graph of incidence between the parts. Depending on the weight of the edges of the graph (in the topology and metric of the dual space) decisive influence or not parts of system.

An exemplary dual space of the landscape can be calculated in advance.
