Realtime Package¶

The realtime package contains the utilities that check data files for corruption during operation and serving the data to external sockets.

Data is checked using pyDARNio. Additional data processing is done using a Python package called backscatter, which is an implementation of the standard FITACF3 algorithm for analyzing SuperDARN data.

This module is standalone and thus not needed to operate a Borealis system. If you do wish to use it, ensure that the realtime_address field in your config file (see Configuration) is set to a device and port that are properly configured. You can test this by running ip addr in a terminal and choosing an internet-connected device that is UP. For example, if you configure realtime_address : "tcp://eth1:9696", then running ip addr should see UP in the eth1 line like so:

3: eth1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP group default qlen 1000
link/ether 04:42:1a:ea:a2:c2 brd ff:ff:ff:ff:ff:ff
altname enp115s0
inet xx.xx.xx.xx/23 brd xx.xx.xx.xx scope global dynamic noprefixroute eth1
   valid_lft 59988sec preferred_lft 59988sec
inet6 xxxx:xxxx:xxxx:xxxx:xxxx:xxxx/64 scope link noprefixroute
   valid_lft forever preferred_lft forever

To disable this module, run the radar with the argument --realtime-off. For example:

/home/radar/borealis/scripts/steamed_hams.py twofsound release --realtime-off
