China ha informado que el UAV solar Caihong-T4 (CH-T4) ha logrado volar por primera vez a una altitud de 20.000 metros, lo cual representa una importante amenaza para la US Navy ya que podría ser capaz de funcionar durante varios meses o incluso años gracias a la ausencia de nubes a esa altura.
De acuerdo con los expertos, el CH-T4 combina un gran tamaño (39 metros de envergadura) y un reducido peso (450-490 Kg), gracias a sus componentes de plástico y fibra de carbono. Puede alcanzar velocidades de hasta 201 km/h y planear a una altitud de hasta 19 kilómetros, lo cual le permite cubrir una superficie de hasta un millón de kilómetros cuadrados.
Todas estas capacidades del CH-T4 permiten al Ejército Popular de Liberación (PLA) poner en peligro a los portaaviones estadounidenses en el Pacífico, ya que permite obtener y proporcionar en tiempo real información de cada objetivo a sus misiles balísticos anti buques, más concretamente al DF-21D, más conocido como "Asesino de Portaaviones".
As the Chungshan Institute of Science and Technology products are not limited to military use, international buyers have expressed interest in buying its products, and the Ministry of National Defense has prepared a list of items that are ready for sale. The Institute is to showcase its products at the Taipei Aerospace and Defense Technology Exhibition in August, with a focus on UAVs, and during this year has attended multiple international events, including the SPIE Defense and Commercial Sensing trade show in California, the International Defense Industry Fair in Istanbul, and the Paris Air Show. In all events, many visitors were interested in the institute’s self-developed defense UAV, named Multi-Functional Laser Sight System.

Aside from the privacy concerns associated with persistent aerial surveillance, there are also worries related to transparency: In Baltimore, Persistent Surveillance Systems (PSS) technology was flown over the city without elected officials (including the mayor), the state’s attorney, or members of the public being informed first. And in Miami-Dade county, the mayor wasn’t aware of Miami-Dade Police Department (MDPD) persistent aerial surveillance plans.
Military equipment has a tendency to make its way from foreign battlefields into the hands of domestic law enforcement. This is a trend that can be useful in investigating crimes, but policies that protect privacy should be in place before snooping airplanes take to the sky, and the public as well as local officials should be informed about the surveillance tools police are using. Persistent Surveillance Systems (PSS), the Ohio-based company that made the sensor system deployed in Baltimore, uses technology originally designed for military operations in Iraq and Afghanistan. This kind of technology has prompted privacy concerns in others cities, with Baltimore being perhaps the most notable.
According to IATA, 65 countries currently have rules for the use of small UAVs. And among EU countries, France is a pioneer: Government decrees already regulate UAV use and parliament has voted in a law coming into force next year that will punish users of UAVs flying over airports and other sensitive areas with fines or prison.
Current common European rules only cover UAVs weighing above 150 kilograms, but small UAVs can be used to deliver services in urban areas, collect data for a wide range of industries, inspect infrastructure, and aid farming. "UAVs mean innovation, new services for citizens, new business models and a huge potential for economic growth," EU Transport Minister Violeta Bulc said in a statement. "We need the EU to be in the driving seat and have a safe UAV services market up and running by 2019. The EU needs to take a leading role worldwide in developing the right framework for this market to flourish, by unleashing the benefits for key economic sectors." added.
The aim is to have the regulatory framework functioning by 2019, with basic services like registration and e-identification. The blueprint unveiled from the European Commission, the EU executive, covers allowing drones to operate in high density under the supervision of fleet operators. The Commission cited estimates that the drone services market could grow up to €127bn in the next few years, so the demand for regulation is increasing with the rising use of drones and the risk of collisions. The European Commission said it hopes negotiations involving the European Parliament and 28 member states will be completed by the end of the year as a key part of the process. The idea is to build a system similar to that of Air Traffic Management for manned aviation, that would supply information to allow UAVs to fly safely and avoid obstacles or collisions.
The International Air Transport Association (IATA), which sets global standards for the aviation industry, counted 856 cases worldwide between January 2013 and August 2015 of a UAV getting too close to a plane for comfort, so the International Civil Aviation Organization (ICAO) is trying to establish a global framework for the future use of UAVs. Fortunately, there have been no collisions to date, the European Aviation Safety Agency (EASA) reported in February.
