Drony Polaków masowo spadają na Helu

Coś dziwnego dzieje się na terenie Trójmiasta i okolic Helu. Wiele osób, które lata w tamtej okolicy dronami informuje, że tracą kontrolę nad swoim dronem DJI, a potem maszyny odlatują w losowych kierunkach i rozbijają się. Co jest powodem tych problemów? Wyjaśniamy poniżej.
Kilkanaście dronów nagle spadło z nieba
Wczoraj o stracie swojego drona poinformowali profesjonalni fotografowie, którzy na instagramie prowadzą skądinąd przecudowny profil b_a_l_t_y_k. Ich dron (DJI Mavic 4 pro) nagle odleciał w losowym kierunku, a potem spadł. Analizując logi po wypadku fotografowie zauważyli, że dron przemieszczał się z prędkością poziomą aż 120 km/h (czyli zdecydowanie szybciej niż ten model potrafi — ale jest logiczne wytłumaczenie tej wartości, o czym niżej).

Po krótkim śledztwie, fotografowie zorientowali się też, że podobne problemy miało jeszcze kilkunastu droniarzy w tej okolicy. I postawili hipotezę, że…
za upadkami mogą stać Rosjanie, którzy zakłócają GPS.
Ale sprawa jest bardziej skomplikowana.
Tak, Rosjanie zakłócają GPS, ale…
Zacznijmy od tego, że Rosjanie faktycznie zakłócają (a dokładniej: spoofują) sygnał GPS z terytorium Królewca (ros. Kaliningradu). Poniżej stan na wczoraj (niebieskim kwadratem zaznaczyliśmy okolice Helu i Trójmiasta):

Ale, po pierwsze, robią to od dawna, a od ponad 2 lat regularnie na terenach Bałtyku, a drony zaczęły spadać dopiero niedawno. A po drugie, sam spoofing GPS, co do zasady, nie powinien powodować “rozbicia się” dronów.
Bo nawet jeśli dron nagle mylnie odczyta swoją lokalizację na podstawie fałszywego sygnału GPS i będzie próbował na tej podstawie “dostosować” swoją pozycję, to pilot wciąż może go kontrolować “ręcznie”. Pozwalają na to np. tryb ATTI (choć trzeba zaznaczyć, że [...]

"GNSS under attack: Recognizing and mitigating jamming and spoofing threats" by GPS World - As costs come down on GPS signal jamming and spoofing techniques, it no longer requires nation-state resources for doing it any more. As attacks become more common, defenses such as signal filters for countermeasures increase too. Self-driving cars and farm machinery may adopt RAIM already in use in aircraft. https://www.gpsworld.com/gnss-under-attack-recognizing-and-mitigating-jamming-and-spoofing-threats/ #GNSS #GPS #Galileo #jamming #spoofing #tech #aviation

A Story of Radio RSA (3): Countering Cairo

An article by German newsmagazine "Der Spiegel" noted in 1984 that the Soviet Union’s global radio propaganda produced more than 2,000 program hours per week in 84 languages1, "and 300 transmitting stations carry Moscow’s message around the world. Likely costs per year: two billion dollars." Also billions were reportedly spent on jamming of broadcasts from Western countries.

There was no question that Radio Moscow, "Radio Peace and Progress", Radio Kiev, Radio Tashkent and other shortwave broadcasters from the USSR were maximum leaders on shortwave. But who counted the "program hours"? Were rebroadcasts of the same programs left out of the count? Did "Der Spiegel" refer to airtime rather than to program times? And were airtime hours multiplied with the number of frequencies used at one time? (They weren’t, as far as I can tell – that would have made Deutsche Welle numbers look implausibly small.

When it came to West Germany’s Deutsche Welle (DW), "Der Spiegel" stated airtime rather than "program hours" – 500 hours per week, in 33 languages and on 27 transmitters. That would mean 2.17 hours daily for every language on average. But of course, German and English had much more airtime than that, and that means correspondingly less for other services.

All the data needs to be taken with a spoonful of salt. According to Magnusson2, DW’s weekly output was closer to 800 than to 500 hours. As for the 33 languages, there is no difference between Magnusson (1976) and "Der Spiegel" (1984), but it seems unlikely that DW should have greatly reduced its airtime during those eight years.

Voice of America, also according to "Der Spiegel" in 1984, spoke only half as many languages as Radio Moscow with only 110 stations and a twentieth of Radio Moscow’s budget. That was to change however: President Reagan wanted a much stronger voice and pledged a billion dollars for the six years from 1984, to modernize and expand VoA’s equipment. The USIA or "United States Information Agency", a precursor of today’s USAGM, saw an increase of 28 per cent year-on-year, and "Radio Martí" was founded, the broadcaster targeting Cuba in Spanish.

Radio RSA had started with 127 hours per week, with May 1966. That would be a quarter of Deutsche Welle andx could be done with the four new 250-kW transmitters newly installed at Bloemendal, south of Johannesburg, but it doesn’t seem unlikely that Paradys, the older station southwest of Bloemfontein, was still involved, too, especially for African audiences. Referencing the World Radio TV Handbook’s 1968 and 1972 editions, Chris Greenway writes that Paradys was listed as still active in 1968, but no longer in 1972.

Based on Magnusson’s statistics3, Radio RSA’s weekly output had risen to 182.8 hours per week by November 1971.

Compared to November 1966, transmission hours to Africa have risen by 4 hours by November 1971, to 98. North America is targeted with 34 hours per week, an increase by eight hours, and Europe is targeted with 35 hours per week, up 29 hours. Here, Europe’s lingual diversity may have been a factor. Radio RSA, by late 1971, had started services in Dutch and in German, although if you go by Magnusson’s data on page 30 there, neither of the two had more than 15 minutes of airtime a day at the time. This seems to suggest that English and French, two services that had been in existence from the beginning, saw most of the increases.

Output would still grow further, to 194 hours in May 1984, but by and large, those 1971 – 1972 numbers define Radio RSA’s weight in the global shortwave broadcasting world in the 1970s and 1980s.

A few categories have changed by May 1984 – Africa, the Middle East and Europe have become more integrated. If that has led to more commonality in programs, I can’t tell. Africa 84.7 hours per week, Africa and Europe 42.7, Africa/Europe/Mideast 13.07, Europe 13.07, and North America 6.53. The airtime for Europe, if divided by half, results in 6.53 hours for the Dutch and 6.53 hours for the German service. While the 1967 and 1971 charts were based on statistics quoted by Magnusson, this chart is based on the May 1984 program schedule provided by Radio RSA.

To base a rough-estimates hitlist based on on another chart by Magnuson (p. 8, itself based on “The Right to Know” and Sveriges Arsbok 1971):

Egypt apparently featured as the leading broadcaster on the African continent, and there was an awareness in Cairo that the country wasn’t only an Arab, but also an African country. Announcing its Swahili programs in 1954, Radio Cairo dedicated the language service to “the liberation of the African continent, in which the Nile flows, from all forms of imperialism”. Indeed, according to Orlik4, South Africa’s apartheid politicians found Radio Cairo’s Swahili language service “particularly ‘vicious'”.

Radio RSA wasn’t a heavyweight, globally speaking, but in its target areas, it could be reliably listened to. The Dutch and German service always ran two parallel frequencies during their daily 56-minutes broadcasts in the 1980s (and probably most of the 1970s), and that also helped Radio RSA’s deft frequency planning. When one originally well-chosen frequency needed to be changed after all, be it because of interference, be it because of poor propagation, such a change could be announced on the remaining scheduled frequency. The same was true for most other language service, although not for every hour on air.

As can be seen by Radio Cairo’s Africa policy, propaganda on the continent wasn’t a one-way street. In fact, Radio Cairo – i. e. Egypt’s foreign radio service – was founded in the early 1950s and had pissed the British off, too, by early 1956. There were even worries in the House of Commons that London might jam those broadcasts.)

While London was worrying about its rule of East Africa, Pretoria worried about clandestine South African radio. Radio Freedom, operated by the African National Congress (ANC) from within South Africa in the early 1960s, before the Rivonia raid5, and from outside South Africa later on.
