To display the status of the firmware ugrade or downgrade, use the show platform hardware slot R0/R1 network-clock | sec GNSS or the show gnss status commands.

While firmware upgrade is in progress, GNSS configuration is not allowed on both, active or standby modules. Syslog messages are displayed to indicate the firmware upgrade start, cancel, SSO during firmware upgrade on standby does not impact firmware upgrade.Īfter firmware upgrade is complete or if firmware upgrade is not required, firmware upgrade progress in the show command is

If the version of the firmware in the software image is greater than the current running verison, firmware is automaticallyĭuring firmware upgrade, the GNSS module status is displayed as not detected and lock status as disabled. When you load this image, the GNSS firmware is copied to the /usr/binos/bin/ directory. GNSS firmware is integrated into the Cisco IOS XE Everestġ6.5.1 image. Each GNSS module must have a separateĬonnection to the antenna in case of an RSP3 switchover. When the GNSS self-survey is restarted using the default gnss slot R0/R1 command in config mode, the 10MHz, 1PPS, and ToD signals are not changed and remain up. The physical location of the router is changed to more than 100 m from it’s pre-reloaded condition. The router is reloaded when the Self-Survey mode is in progress When the router is reloaded, it always comes up in the OD mode unless: GLONASS and BeiDou satellites cannot be enabled simultaneously. However, the module uses configured satellites only in the OD mode. You can configure the GNSS module to automatically track any satellite or configure it to explicitly use a specific constellation.

This detection causes an automatic restart of theĪ manual restart of the self-survey mode or when the stored reference position is deleted.Ī worst-case recovery option after a jamming-detection condition that cannot be resolved with other methods. The GNSS module stays in the OD mode unless one of the following conditions occur:Ī position relocation of the antenna of more than 100 meters is detected. If you want to change the trackingĭata, use the no shutdown command to set the GNSS interface to its default value. The router saves the tracking data, which is retained even when the router is reloaded. In this mode, the module only processes the timing informationīased on satellite positions captured in self-survey mode. Position information is stored in non-volatile memory on the router. Over determined clock mode-The router switches to over determined (OD) mode when the self-survey mode is complete and the State is considered good enough to lock to GNSS. The quality of the signal in Self-Survey mode with State, you can start using the 1PPS, 10 MHz, and ToD inputs from GNSS. Is able to generate accurate timing signals and achieve a Normal or Phase-locked state. This operation takes about 35-to-40 minutes. Longitude, and Height) of it current position. It tries to lock on to minimum fourĭifferent satellites and computes approximately 2000 different positions of the satellites to obtain a 3-D location (Latitude, Self-Survey Mode-When the router is reset, the GNSS module comes up in self-survey mode. The GNSS module has the following stages of acquiring and providing timing signals to the Cisco router: Signals from the GNSS module (when enabled) take precedence over those of the external source.īy default, anti-jamming is enabled on the GNSS module. The RSP3 module can also receive 1PPS, 10 MHz, and ToD signals from an external clocking and timing source. To synchronize broadband wireless, aggregation and pre-aggregation routers, and an accurate time-of-day (ToD). GNSS provides an accurate one pulse-per-second (PPS), a stable 10 MHz frequency output When connected to an external antenna, the module can acquire satellite signals and track up to 32 GNSS satellites, and compute The following table explains the different LED status. The GNSS LED on the RSP3 front panel indicates the status of the module.
