[*1] It has eight anti-jamming functions for CW waves.
[*2] Time Receiver Autonomous Integrity Monitoring (T-RAIM) is a mechanism to identify and eliminate satellites that may have a
bad influence on the positioning calculation by combining and principle of majority when the number of satellites in use is
larger than the minimum number of satellites required for positioning.
[*3] This product has a function to notify an alarm by detecting a spoofing signal, and to eliminate the decoding of spoofing signal.
Please refer to the eSIP Protocol Specifications for details.
[*4] A sudden temperature change may disturb the frequency of the TCXO installed inside, possibly causing instantaneous
satellite reception failure. Especially when installing a fan, it is recommended to take care not to blow the wind directly to
this product.
