If your organisation\ndepends on accurate time, then mark the 6th<\/sup> April 2019 in your\ndiary\u2014it\u2019s GPS rollover week.<\/strong><\/p>\n\n\n\n

On this day, the binary number that the GPS system uses to\nencode the time will reach its limit and tick over back to zero. If your hardware\nisn\u2019t compatible, you could end up with unsynchronised systems and devices that\nthink it\u2019s years in the past. <\/p>\n\n\n\n

Don\u2019t worry, though, you might not need to take any action\u2014it\nall depends on the type of GPS receiver you\u2019re using. Even if you think you\nwill have problems, the solution is as simple as upgrading your antenna.<\/p>\n\n\n\n

Here\u2019s everything you need to know to keep things ticking\nalong in your business.<\/p>\n\n\n\n

What is GPS Rollover Week?<\/h2>\n\n\n\n

All over the world, businesses, organisations and governments use time derived from the GPS system to timestamp their operations and synchronise their critical systems<\/a>. <\/p>\n\n\n\n

\"GPS
GPS time is typically supplied to connected devices via an antenna and a time server.<\/strong><\/figcaption><\/figure><\/div>\n\n\n\n

The GPS system transmits the date and time as a 10-bit number that indicates the week and the number of seconds into that week. Your GPS receiver turns that into the day\u2013month\u2013year format you\u2019re familiar with. <\/p>\n\n\n\n

It\u2019s a highly accurate system, but when the 10-bit number\nreaches its maximum\u2014after 1,024 weeks, or 19.7 years\u2014it ticks back over to the\nstart. <\/p>\n\n\n\n

The GPS system went live in 1980, meaning it rolled over for\nthe first time in 1999, ending what was known as the first epoch of GPS time. <\/p>\n\n\n\n

It will roll over again on the 6th<\/sup> April this year, bringing to an end the second epoch and causing problems for devices that aren\u2019t ready for it.<\/p>\n\n\n\n

What Should You Do About It?<\/h2>\n\n\n\n

If you depend on GPS time to coordinate your operations,\ntimestamp your transactions or synchronise your processes, then you probably\ncan\u2019t afford to let those systems think it\u2019s decades in the past.<\/p>\n\n\n\n

Thankfully, users of Galleon Systems products have nothing\nto worry about.<\/p>\n\n\n\n

The first thing to do is check which GPS receiver<\/a> you\u2019re using. If it\u2019s a mushroom-style antenna, then you don\u2019t need to do anything.  <\/p>\n\n\n\n

\"GPS
Mushroom antennas are already compatible with rollover week. <\/strong> <\/figcaption><\/figure>\n\n\n\n

These newer antennas are fully compatible with GPS rollover\nweek, meaning your critical processes will continue to run as normal.<\/p>\n\n\n\n

However, if you\u2019re using a box-style GPS antenna, then you need to take action.<\/p>\n\n\n\n

These older receivers are no longer supplied or supported by Galleon Systems, and their compatibility with GPS rollover week is unconfirmed.<\/p>\n\n\n\n

\"GPS<\/figure><\/div>\n\n\n\n
\"\"
A box-style antenna will need to be upgraded.<\/strong><\/figcaption><\/figure><\/div>\n\n\n\n

To ensure your time-dependent systems continue to run as normal, you should upgrade your antenna now.<\/p>\n\n\n\n

April 6th<\/sup> is fast approaching, but Galleon Systems can supply you with a mushroom antenna immediately, and our technical support department can provide any help you need to get it installed in time. <\/p>\n\n\n\n
