PALSupport Veristore Record and Replay Solutions for Air Traffic Control
PALSupport (UK) is an industry leader in the manufacture of Recording Solutions for Air Traffic Control (ATC).
Designed specifically for ATC, a Veristore Record and Replay System records and synchronously replays voice signals, ambient microphones, raw radar data, controller screen information and CCTV camera signals.
Every system is fully compliant with the latest ICAO standards, modular in concept and easy to expand or upgrade when dictated by operational requirements or regulations.
Veristore Recorders for ATC
All Veristore Recorders have the following features:
- The User has no access to the record process, which is totally independent of the Veristore Software used to access the recorded data.
- Data is written directly to the recorder internal store. Once written, it is totally secure and cannot be altered, corrupted, overwritten or deleted during the regulatory retention period.
- A read-after-write check is performed immediately after the data is written to disk and an alarm is raised if an error is identified.
- True 100% redundancy is achieved by using two recorders in parallel. These recorders do not communicate with each other and hence no data can ever be lost due to switchover between ‘master’ and ‘stand-by’ equipment. This results in two totally independent, complete and accurate, copies of the recorded data which means that there is usually no legal requirement to archive the data.
Veristore Voice Recorders
Veristore Voice Recorders utilise COTS Linux server technology and have interfaces for many data technologies and formats, whether analogue, digital or VoIP.
- Data is recorded continuously 24/7, without the use of either VOX or AGC, which guarantees that all of the information is captured and can be replayed exactly as the controller heard it.
- Ambient Microphones may be recorded alongside the communications information and are password protected during replay.
Veristore Radar Recorders
The ICAO SARPS state that both Through-the-Wall (TTW) Radar and At-the-Glass (ATG) Radar are to be recorded and replayed synchronously with the voice data.
- TTW Radar is raw, pre-processed, radar data and recorded at the point where the radar signal ‘enters the building’. It is transmitted as either a serial data stream or in IP Format. Veristore recorders have interfaces for both.
- ATG Radar records the Controller Display by capturing the screen drive signal. A Splitter, which does not degrade the information displayed on the Controller Screen, is introduced as close as possible to the Screen and a Frame Grabber then captures individual frames and transmits them to the Veristore Screen Recorder which has interfaces for virtually every type and resolution of screen from Analogue RGB to DisplayPort.
PALSupport (UK) recommends that a nominal frame capture rate of 3fps is used. This enables mouse movements, manipulation of the displayed data and the opening and closing of any windows to be faithfully captured.
Veristore CCTV Recorders
The Veristore CCTV Recorder has the same architecture as the Veristore Screen Recorder with interfaces for most cameras including AHD and HD IP.
Veristore Replay for ATC
Any of the recorded data can be immediately replayed at either the Central Management System or a Remote Replayer.
- TTW Radar Data is displayed on local area maps. The replayed radar display can then be directly compared with the information displayed on the controller screen at the time of recording. This will confirm whether or not the controller was able to see all of the salient details at the time of an incident and that nothing had been masked or hidden from view.
- When the ATG Radar Data is replayed the controller screens are displayed exactly as they were captured. Mouse movements, the opening, closing and scaling of windows and any manipulation of the display initiated by the controller are replayed exactly as they occurred.
- Recorded data needed for an investigation may be impounded by the relevant regulatory body. When this happens, the appropriate data will be copied to a ‘Quarantine Storage’ location, which is a separate, secure storage area. Quarantine (impound) files are complete, accurate and verifiable.
Veristore Central Management System (CMS)
The Central Management System (CMS) is the hub of a Veristore Record and Replay System, communicating with all of the recorders via the Veristore Ethernet Network.
- A straightforward, intuitive, Graphical User Interface enables the user to quickly and efficiently access the recorded data and the status of the recorders.
- A comprehensive overview of the current status of all of the recorders and the status of each channel is readily available with the information clearly displayed on a single screen.
- All of the recorded data can be accessed for live monitoring, replay or copying to an alternative storage location.
- The security and integrity of the Record and Replay System is maintained by a hierarchy of user types and passwords, which are the responsibility of the system administrator.
Veristore System Alarms
Veristore Record and Replay Systems have a comprehensive alarm structure, which is flexible and may be tailored by the user to their specific requirements.
- Contact closure alarm signals are generated by the Recorders if a fault is detected that causes the recorder to stop recording. These signals are independent of the Veristore Software and can be directly connected to a Remote Alarm Panel.
- The CMS and Recorders also generate alarm signals, which may be designated as ‘urgent’ or ‘non-urgent’ to indicate that a fault in the Recording System has been identified.
Veristore System Log and Alarm Log
Detailed System and Alarm Logs are produced and maintained by each of the Recorders. The CMS interrogates the Recorders and compiles the information into System and Alarm Logs for the Record and Replay System.
- All of the entries in the logs are time-stamped and have the relevant user identification attached. Any access to the recorders is therefore reported by user identification, date and time.
- The Alarm Log provides details of all of the alarms that have been raised, when they were acknowledged, if the fault has been rectified, and when they were cleared.
