Why are all your Receivers Dual Channel Parallel?

All our receivers are dual-channel parallel because this ensures optimal performance and reliability when monitoring AIS signals. AIS operates on two dedicated VHF frequencies, channel A (161.975 MHz) and channel B (162.025 MHz). A dual-channel parallel receiver is designed to monitor both channels simultaneously, rather than switching between them. This approach offers several key advantages:

1. No Loss of Data: By monitoring both AIS channels in parallel, there is no risk of missing transmissions. Single-channel receivers that alternate between channels can occasionally fail to capture signals, particularly in busy areas where AIS traffic is high.
2. Faster Updates: Dual-channel parallel reception ensures that AIS data updates are more frequent. This is especially critical in dynamic environments where vessel movements and positions are constantly changing.
3. Enhanced Safety: For users relying on AIS for navigation and situational awareness, having real-time information from both channels ensures maximum safety. This is particularly important in congested waterways or during poor visibility conditions.
4. Compliance with Standards: Many maritime authorities and organisations recommend or require the use of dual-channel receivers to ensure comprehensive AIS data collection and compliance with international standards (e.g., IMO and ITU requirements).
5. Ideal for Busy Areas: In high-traffic areas such as ports or shipping lanes, where vessels may transmit on either channel A or B, dual-channel parallel receivers ensure that all transmissions are received without delay or interruption.

By equipping all our receivers with dual-channel parallel technology, we provide users with robust, reliable, and high-performance AIS solutions, ensuring they receive the full range of AIS data for safe and efficient maritime operations.
