Three GLONASS satellites lost in fiery crash

In a repeat of a late 2010 disaster, three Russian GLONASS satellites were lost this morning in a fiery crash shortly after takeoff. The Proton-M rocket carrying them broke up and hit the ground within a minute of takeoff. read more

The newly announced Garmin Oregon 650t

UPDATERead our hands on Garmin Oregon 650 review.

As we predicted, Garmin is updating their Oregon handheld line by adding GLONASS capabilities. But they didn’t stop there; the newest Oregons have a bevy of new features and improvements. Read on for the details. read more

Search and rescue capability coming to GPS, GLONASS and Galileo

For many years now, satellite-aided search and rescue notification has been available using personal locator beacons (PLBs). Cospas-Sarsat, as this service is officially known, utilizes geosynchronous and low earth orbit satellites. This results in a couple of limitations — the need to have a direct line of sight to a transmitter (for the former), and the possibility that multiple orbits may be required to independently establish a position (for the latter). read more

GLONASS infographic

glonass-infographicSince we now have a consumer handheld that can utilize the Russian GLONASS constellation, I couldn’t resist posting this. My apologies for the poor quality of the image. ITAR-TASS apparently sells these, so there are probably better images available, but the “buy” link takes you to a Russian language only page.

GLONASS in my hand

GLONASS on eTrex

UPDATE: Here’s my hands on review of the eTrex 20, including an evaluation of it’s performance.

Well this is the coolest thing I’ve seen on a GPS receiver in a long time. I picked up the new eTrex 20 yesterday and was happy to see that, as advertised, it promptly locked on to not only GPS satellites, but Russian GLONASS birds as well.

As far as I know, this is the first consumer receiver to feature GLONASS in the US. I know there is at least one smartphone available in Russia with it, but I’m not sure what else is out there.

We’ve seen recent reports suggesting GLONASS will improve reception in northerly latitudes and urban canyons. If you’ve got an eTrex to test in those environments, we’d love to hear from you. Chime in below!

GLONASS to outperform GPS in northerly latitudes?

GLONASS-KIs there a GLONASS receiver in your future? You may be more motivated if you live at a northerly latitude. A Swedish firm, Swepos, which demands one-meter accuracy for their work, has integrated the Russian system into their operations, saying…

"It functions somewhat better at northern latitudes because its satellite orbits are located higher in the sky and we see them better than we do the GPS satellites," said Bo Jonsson, deputy head of a geodesic research unit at Swepos.

Three Russian GLONASS satellites end up in Pacific

GLONASS-Proton-rocketOuch! Three Russian GLONASS satellites carried atop a Proton rocket (pictured above) crashed into the Pacific after veering off course by eight degrees. It is believed that they went down near Hawaii. Apparently rocket separation failed to occur until a higher than planned altitude.
