White paper
NISHINOMIYA, HYOGO, JAPAN, Might 9, 2024 /EINPresswire.com/ — FURUNO ELECTRIC CO., LTD., (“FURUNO”) has launched the GT-100, a twin band GNSS receiver for time synchronization that may concurrently obtain L1 band (1575.42 MHz) and L5 band (1176.45 MHz) GNSS satellite tv for pc indicators.
Multipath Mitigation and anti-jamming measures should be thought of to attenuate degradation of time accuracy, even when antennas are put in in city areas or close to home windows.
When there are buildings close by, the indicators from GNSS satellites could be anticipated to be mirrored off them at numerous angles. This example is called a “multipath” state of affairs. If there are obstacles within the line of sight, the indicators might be diffracted and/or mirrored by these obstacles. This may trigger giant errors to creep into place and time calculations carried out utilizing these indicators because of the uncertainty in noise elements that change relying on components comparable to how the impediment affected the sign, and the way a lot of a detour the indicators needed to make.
Additionally, for the GNSS receiver to calculate the place, time, and many others., it’s essential to obtain the GNSS sign utilizing a devoted GNSS antenna. Nevertheless, for the reason that GNSS sign broadcast from the satellite tv for pc could be very weak initially, if there may be different unintentional noise supply or sign supply across the antenna, it prevails as a jamming sign, and the GNSS sign might have drawback with regular reception.
There are cell phone base stations which can be liable to intrude with 1575.42 MHz indicators, and when utilizing GNSS receivers in city areas, there’s additionally the danger of unanticipated jamming wave sources comparable to passersby and autos.
Our earlier single band receiver, praised for delivering time synchronization stability of lower than 4.5 ns (1 sigma) and its Dynamic Satellite tv for pc Choice™ multipath countermeasures expertise for lowering accuracy degradation in city environments and close to home windows, has been enhanced by including twin band help.
Greater than merely doubling the variety of indicators that may be obtained, twin band functionality considerably improves robustness concerning jamming and different potential disruptions by permitting using two completely different frequency bands.
Such enhanced options give customers a excessive degree of confidence in fields that require excessive reliability, comparable to 5G cell base stations, monetary transactions, and energy grids.
“GT-100” which is one in every of these GNSS receivers, is full-featured extremely sturdy mannequin, supporting dual-frequency band reception (L1 and L5).
The above are some extracts from the white paper. Our engineer specializing in time synchronization explains the significance of robustness by utilizing twin band GNSS receivers in over 20 pages.
