Receivers are required to disambiguate this to the correct date, but may have difficulty due to not knowing time to within half this interval, or may have bugs. With this configuration, ntpd will read the timestamp posted by gpsd every 16 seconds and send it to unit 0. Some other sentences can be enabled. Unit 0 is used for message-decoded time and unit 1 for the more accurate, when available time derived from the PPS synchronization pulse. This device was supported by GPSD up to release 2.

No gpsd configuration is required to talk to chronyd. Uses SiRF firmware version To tell the daemon that a device has been disconnected and is no longer available, send a minus sign ‘-‘ followed by the device name followed by LF or CR-LF.

The best indoor performer I have tested. This is 1, times more precision than the time resolution provided to ntpd.

This control channel is separate from the public gpsd service port, and only locally accessible, in order to prevent remote denial-of-service and spoofing attacks.

I gls to the Terms and Privacy Statement.
The shared-memory interface is intended primarily for embedded deployments in which gpsd monitors a single device, and its antarix advantage is that a daemon instance configured with shared memory but without the sockets interface loses a significant amount of runtime weight. FLASH based program memory. Not a complete GPS, but a chipset.
Atmel and u-blox Introduce Single-chip GPS Receiver
In that case no invocation is required at all. Clients with an assigned device in polling mode are subject to a longer timeout 15 minutes. The computation does not exactly match what SiRF chips do internally, which includes some satellite weighting using parameters gpsd cannot see.
Raymond, Chris Kuethe, Gary Miller. Firmware updates are available from ublox; the update is strongly recommended as hsb fixes a number of UBX bugs, and adds useful new features. Reported by walkie mail. While the technical information claims 1us accuracy on the clock, the interface is undocumented, so there anraris no way to know if there is a usable 1PPS signal. NTP offset quoted is at bps; drops to 0. To send a control string to a specified device, write to the control socket a ‘!
