Settings / AIS Sharing
SEAiq AIS Sharing is an easy way to get AIS information for many parts of the world.
AIS Sharing has two sources of data. First, it provides access to all the feeds at the AIS Hub. AIS Hub is a cooperative way to get AIS data; people or organizations setup permanent AIS antennas and supply their feed to AIS Hub. In return AIS Hub sends that feed to the organizations. If you want to add AIS coverage for your area and it is not already provided, AIS Hub is one way to do that.
Devices such as Apple iPads and iPhones will normally turn off their cellular internet connection when they connect to a WiFi network. You can follow these instructions in order find different approaches to having both connections active at the same time.
If you have a local AIS base station that you would like included in AIS Sharing, you can email us at email@example.com with an IP address and TCP or UDP port. We can add the feed directly to the SEAiq server.
- AIS Sharing: Enable connection to AIS Sharing server.
- Diagnostics: See diagnostics information on your connection to AIS Sharing.
Hi-Res PPU Data
- Transmit Own-Ship: (Only SEAiq Pilot) Enabling this causes your Own-Ship information to be transmitted to other vessels.
This differs from normal AIS data in that it does not require AIS support for your vessel. Also, the information transmitted includes any adjustments you have made to the vessel's size and/or antenna offsets. Finally, the name of the pilot is included in the data that is shared.
If this option is enabled on more than one instance SEAiq on the same vessel, then you can see other images for Own-Ship. This can be helpful if you have several pilots with their own PPUs on a vessel and they want to cross-check their positions with each other. If the devices are using the same PPU, then the additional instances only create clutter and you may want to turn off Transmit Own-Ship for all but one.
- Show Vessels: (Only SEAiq Pilot) Enabling this causes other vessels sharing Hi-Res PPU data to be received and displayed.
Note that you can not see your own data here. This only has an effect if someone else is transmitting data.
- Hide Matching AIS: (Only SEAiq Pilot) Enabling this causes the AIS targets matching a Hi-Res PPU to be suppressed. This is done to reduce clutter. The AIS data is only suppressed when Hi-Res PPU information about a vessel is complete: it should contain GPS position, COG, SOG, HDG, ROT, size, and antenna offset.
- Use Alternate Service: (Only SEAiq Pilot) Use alternate AIS Sharing server. This is normally left disabled unless you are using an alternate service.
- Service: (Only SEAiq Pilot) Use this service name to choose an alternate AIS service. This is not normally required and you should not change this without instructions from your administrator.
- User Name: (Only SEAiq Pilot) Use this username to login to an alternate AIS service. This is not normally required.
- Password: (Only SEAiq Pilot) Use this password to login to alternate AIS service. This is not normally required.
Frequently Asked Questions
- Can I use AIS Sharing without having my own AIS hardware? Yes.
- Can I use AIS Sharing while also using my own AIS hardware? Yes.
- Can I use AIS Sharing with my own AIS hardware but not share my own feed? No. When both WiFi NMEA/AIS and AIS Sharing are on, SEAiq will always attempt to share your AIS feed with other users. If other users are around, they may be sharing their feed with you!
- What if a target is listed in both my WiFi AIS feed and AIS Sharing? Your WiFi AIS feed is always given precedence over AIS Sharing?
- What data is shared about my vessel? Your own vessel's location is only shared when SEAiq is connected to an AIS feed for your vessel's AIS transponder. Note that in this case your AIS transponder is already broadcasting your vessel's position on VHF; other AIS internet data services may be listening to your AIS broadcasts on VHF. If you have an AIS receiver (not a transponder), then only data received over VHF for other vessels is shared.
- How do I both connect to a WiFi NMEA/AIS and use cellular internet connection? Read these instructions.
- Are targets from AIS Sharing recorded? No. Only data received from your actual NMEA/AIS stream is used.
