Electronic navigation charts management with public hydrographic web map

read more

We are prepared to transform your hydrographic data into a web-based Hydrographic Database Management System with GIS tools (HIS).

HIS is an information system for managing and presenting data from hydrographic surveys.

It can also produce high quality fairsheets to simplify the process of the production of electronic navigational charts.

Maritime safety


Hydrographers and Cartographers can take decisions based on location information. It is a vital feature considering the constant changing of the underwater situation.

The system consists of two main parts: a seamless database of depths (soundings) and a database of objects. The objects for the system are collected from hydrographic surveys – survey areas, wrecks, navigational marks, rocks and obstructions.

For every object extensive information can be stored in HIS, containing its location, classification and attributes, and also images. HIS also provides a wide range of user-friendly GIS management tools for managing and presenting surveyed data.

Central ePrescription system and its interfaces

By 2013

Three years and 300 000 €

Hannes Danilov, the member of the board at the Health Insurance Fund

We are pleased to say that we have a digital prescription system that is a model for other countries

In the search for efficiency and excellence, the Estonian Health Insurance Fund and the Ministry of Social Affairs started the project of e-Prescription in Estonia.

The paper prescription system, that was in use before, wasted the time of all parties involved in the prescribing and buying/selling of medications.

The scarce resource of a doctor’s appointment time was wasted on writing recurring prescriptions and the patients had to spend time waiting for their appointment.

Some prescriptions would get lost, some would include the wrong percentage of subsidy by the Health Insurance Fund. The collection of statistics and data is costly and all parties must waste time on reporting the same data at different times. The new system was designed as a centralized and paperless system to be used by all doctors, patients and pharmacies.

The central system was developed by the state in cooperation with Helmes. The information systems of medical practices and pharmacies were integrated and updated by their service providers. Helmes also developed a central online interface for doctors and pharmacies who have less prescriptions to process or whose developments were not ready by the time of launching e-Prescription.

Serving civil air traffic control data to military air surveillance

read more

Secondary surveillance radar (SSR) is a radar system used in air traffic control (ATC), that not only detects and measures the position of aircraft i.e. range and bearing, but also requests additional information from the aircraft itself such as its identity and altitude.

Unlike primary radar systems that measure only the range and bearing of targets by detecting reflected radio signals, SSR relies on targets equipped with a radar transponder, which replies to each interrogation signal by transmitting a response containing encoded data.

SSR is based on the military identification friend or foe (IFF) technology originally developed during World War II and therefore the two systems are still compatible.

  • The secondary Source radar identifies a flying objects in the air space, with SSR code
  • A civil air traffic control operators then identifies the unknown flying object, and associates the SSR code with the appropriate civil flight number
  • The association then has to be served for military air surveillance as soon as possible. This means in real-time.

 The flight associations are available in the civil air control system in form of:

  • Online Data Interchange (OLDI) transit messages from other air traffic control systems
  • New flight associations created by the operator of the air traffic controller workstation

 The custom made information system developed by R-Systems Ltd

  • extracts the necessary data (1-2% of all of the data)
  • composes the messages according to the Online Data Interchange (OLDI) format, a standard by European Organization for the Safety of Air Navigation.
  • combines OLDI messages with the Aeronautical Fixed Telecommunication Network (AFTN) messages from flight plans
  • transmits everything to the military air surveillance system

Flightwatch For Airport

  • The FlightWatch Server
  • The link to Air Traffic Control center
  • The Airport Dispatcher Workstation
  • The Radar and Flight Data Monitors
  • Noise Monitoring System

For linking the flights with radar data the FlightWatch system exploits the associations between the radar code and the flight plan created by air traffic controllers. The flights are determined according to the flight CallSign. The active flights table is created, where the flight plan data is collected and relevant changes are made. The active flights table is supplemented with the secondary source radar (SSR) code after the air traffic controller has made the appropriate association.

The result is displayed int workstations on cartographic background.

Comprehensive hydrographic survey software

ran

The primary task of the survey software is to collect and store bathymetric data.

It also provides tools for survey planning and data visualization.

Among the possibilities of the software is also the analysis of the quality and sufficiency of the collected data.

aegir

The task of the cleaning software is to check and filter out erroneous bathymetric data.

As a result, trustworthy soundings are obtained, which can be issued and also used for the analysis of the bottom relief.

Among the possibilities of the cleaning software is also marking of the discovered underwater objects directly on the chart.

Radar Filter

read more

The Radar Filter reads signals from radar, analyses and filters them according to the pre-determined conditions – limited areas and height ranges.

The transmission of the radar data (both reading and forwarding) is based on the ASTERIX (All Purpose Structured Eurocontrol Standard for Radar Information Exchange) format -, which is defined by the standard document Eurocontrol Standard for Radar Data Exchange. 

The filtering conditions of the radar data are determined by a filtering algorithm and its changeable configuration.

The Radar Filter processes and releases only ASTERIX CAT 001 radar plot messages described in the previously mentioned standard sub-document Part 2a - Transmission of Monoradar Target Reports. All other messages, though received, are not released on any conditions.

The filtering of radar messages is carried out on the basis of:

  •  geographically predefined areas
  •  height ranges
  •  message types
  •  data field selection

There may be several areas and height ranges and the filtering conditions can be combined. Both the input and the output of the Radar Filter are unidirectional. No data is sent to the radar and no data is received from the output port. In addition to the software level the uni directionality of the data flow can be supported on hardware level (cabling).
