Pictured above are two of GLONASS / GPS navigator "NII gallakticheskogo instrument": Right — the equipment of the previous generation 14TS822 "Grotto-M" on the left — the new standard, which has the same title as the prior — "Grotto-M ", but is a deep modernization of the younger brother.
First "Grotto", released in 2003, is in service with the Russian army, a number of countries in Africa and Latin America (Navigator menu has English, French and Spanish versions), and produced a circulation of 10 thousand copies. In our military is used, in the main, the commanders of artillery units, exploration, mining and arrows parts for special purposes. According to the state it is necessary to have in the motorized rifle battalion, and company tactical groups operating in isolation from the main force.
Casing of your device is made from a single bar of aluminum milling process, which leads to a higher strength of the product, but just significantly increase the weight of it (the device weighs 800 grams). Since the product is initially 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, equipped with navigation keys bolshennymi who loved the end user — the military
Included were two BATTERY, which due to the design elongated body up to 25 cm
As the time goes on and the technology goes ahead, now in the active procedure was carried out profound modernization of the navigator, which almost led to the creation of a completely new device, but under the same name — "Grotto-M ". Article has received a new 32-bit microprocessor ARM, large color screen with a resolution of 320×240. Buttons were moved to a higher part of the browser, so how exactly at this location device it is most convenient in the hand and pressing the buttons more comfortable.
From the touch screen refused because in the criteria for cool climate and hands with gloves it's just useless.
The case was plastic, power supplies found other accommodations.
Used lithium-polymer battery 2500 mAh for French production, as Russian manufacturers supply parts explained that very busy with orders and fail to deliver their products earlier than a couple of years
Navigator can work on Unit 1 BATTERY, but then its running time is reduced. Navigator when the air temperature is above zero degrees works about 18 hours without annoying at very low temperature, which is calculated (-30 degrees), — more than 12 hours.
Apart from the battery pack product can operate on ordinary AA batteries AA
Navigator can withstand submersion at a depth of 1 meter for a day and can then work with.
"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. Charge the BATT can be both in the device itself, 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 at the moment the website refreshed evidence that it is less than 1 W, and this means that the expected shift took place in the 110-nm process.
It should be noted that the power consumption of devices based on GLONASS will always be more of these kinds of devices based on GPS, as the Russian navigation system uses a wider range of frequencies. Wide channel harder to suppress electronic warfare, but this advantage is exchanged for a superior power.
Navigator can run up to 32 satellites, which greatly increases the accuracy of the positioning. She (accuracy) is dependent 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 similar indicators of the South American military navigator DAGR. The differential mode is also implemented in the Russian navigator, which allows using the base station increment positioning accuracy
of up to 10 cm s
"Cave-M" to the outside navigation antenna. The antenna has a magnet and can be used when driving a car
At the request of the customer is likely setting slots for SD-card flash memory, but the military is not required for such abilities. The internal memory of the device is of 256 mb.
Beloved question all the readers I have been asked: "Whose production electric component navigator." Chip is fully developed in the enterprise, not counting the core microprocessor, which is bought under license. Circuitry of the digital portion of the topology — all Russian, but the physical and Load — China, Taiwan. Installing the card again is going on in our country. Monitors also zatarivaemsya abroad, as Belarusian developers (candidate countries) offer a model with a huge power consumption, weight and price.
Navigator allows you to record the route and display 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 navigator with operating systems based on Linux and Windows. It is understood that, if desired, the user will be able to install in the "Grotto" any card from foreign developers, using a special converter software package.
Navigator service can solve puzzles that are necessary for the needs of artillery:
— According to the coordinates, distance and azimuth determined coordinates of the point you want to shoot at;
— According to the two pairs of coordinates to determine the distance and azimuth between them;
— the coordinates of 2-point and corner between them to determine the coordinates of the third point;
— measuring the azimuth angle, etc.
Probable conversion of latitude and longitude coordinates in Gauss-Kruger and back.

Now "NII gallakticheskogo instrument" in an active manner develops the latest model of the navigator, which will have to change the worn "Grot-M" and Ammunition standard 14TS821 "In the Grotto" which currently used by armored Russian armed forces.
