GLONASS / GPS navigation device Grot-M

Blogger Denis Mokrushin published a post with a review of the new browser GLONASS / GPS from the national developer of "Institute of Space Device Engineering."

In the photo above two GLONASS / GPS navigator of "Institute of Space Device": the right — the previous generation equipment 14TS822 "Grotto-M" on the left — a new model that has the same name as the previous one — "Grot-M", but is a deep modernization of the younger brother.

The first "Grotto", released in 2003, is in service with the Russian army, as well as several countries in Africa and Latin America (Navigator menu has English, French and Spanish versions), and produced a circulation of 10 thousand copies. In our armed forces is used primarily by commanders of artillery units, exploration, mining and arrows parts for special purposes. According to the state it is necessary to have in the infantry battalion and company tactical groups operating in isolation from the main body.
Casing of your device is made of a single bar of aluminum milling method that causes the high strength of the product, but also significantly increase the weight of it (the weight of the device was 800 grams). Since the instrument was originally intended only to determine the origin and objectives in the artillery, he got a small screen and did not support the display of maps. For convenience in the bitter cold when wearing gloves, the navigator equipped with large buttons that are very popular with end users — military

As time goes on and the technology goes ahead, now on its own initiative was held deep modernization of the browser, which in fact led to the creation of a completely new device, but under the same name — "Grotto-M". The product has received a new 32-bit processor ARM, large color display with a resolution of 320×240. The buttons have been moved to the top of the browser, as it is in this location is most convenient instrument in the hand and pressing the buttons for the most comfortable.

From the touch screen refused because in cold climates and hands with gloves it's just useless.

The case has a plastic, power supplies found another location.

Navigator withstand submersion at a depth of 1 meter for the night and may thereafter operate.
"Grotto" can be connected to networks with a low voltage (10 to 30 volts), which allows you to charge it from the electrical system of cars and armored vehicles. When charging battery packs as possible in the unit, or in a separate charger.
At the moment of contact with the developers (August 2011) Navigator energy is effected at 130 nm process, was 1.05-1.1 W (at the peak of up to 1.2 watts), but now the site updated data that it is not more than 1 watt, which means expected transition that took place at 110 nm process.
It should be noted that the power consumption of devices based on GLONASS will always be more similar devices based on GPS, as the domestic navigation system uses a wider range of frequencies. Wide channel harder to suppress electronic warfare, but this advantage is exchanged for higher power consumption.

Navigator can operate simultaneously with the satellites 32, which significantly improves the accuracy of positioning. She (accuracy) depends on many factors (the number of satellites, terrain, etc.) and for the "Grotto" is 10 m (mode of operation, where the interaction is only with satellites), which is comparable with those of the U.S. military navigator DAGR. The differential mode is also implemented in the domestic Navigator, which allows using the base stations to increase the accuracy of positioning to tens of centimeters.
"Cave-M" with external navigation antenna. The antenna has a magnet and can be used when driving a car

On demand, the installation slots for SD-card flash memory, but the military has not asked about the possibility. The internal memory of the device is of 256 MB.
My favorite question of my readers were asked: "Whose production of electronic component navigator." Chip developed entirely at the company, other than the CPU core, which is purchased under license. Circuitry of the digital portion of the topology — all domestic, but the physical production — China, Taiwan. Mounting board again is ours. The displays also purchased abroad, as Belarusian developers (an alternative to foreign countries) offer a model with a large power consumption, weight and cost.

Navigator allows you to record the route and show it on a map background. Maps, directions can be poured into the device and take it with via USB (port for USB, RS-232 and RS-485 alone, the bundle includes a splitter). Included with the product is software that allows the end user to match the navigator with operating systems based on Linux and Windows. It is assumed that, if desired, the user can install a "Grotto" any cards from third-party developers, using a special adapter included with the software.
Navigator can solve service tasks that are necessary for the needs of artillery:
— Given the coordinates, distance and azimuth determined coordinates of the point you want to shoot at;
— For given two pairs of coordinates to determine the distance and bearing between them;
— The coordinates of two points and the angle between them to determine the coordinates of the third point;
— Measurement of the azimuth angle, etc.
Possible conversion of longitude and latitude coordinates of the Gauss-Kruger and back.

Currently JSC "Research Institute of Space Instrument" on its own initiative is developing a new model of the Navigator, which is to replace worn "Grotto-M" and Ammunition sample 14TS821 "Grot-B", which is now used by armored Russian armed forces. [/ Cut]
