El Arenosillo Test Centre (CEDEA) is the name of a rocket launch site for suborbital rockets managed by INTA, located near Mazagón in Spain.[2] It is located in the province of Huelva, Andalucía, in the southwest coast of Spain (37.1° N, 6.7° W).[3] CEDEA is adjacent to the Center of Excellence for Unmanned Systems (CEUS). El Arenosillo is also the location of an autonomous astronomical observatory of the BOOTES network , with two domes and three telescopes.

El Arenosillo Test Centre (CEDEA)

Formation	4 October 1966[1]
Type	rocket launch site
Location	Mazagón, Spain
Coordinates	37.09687°N 6.73863°W / 37.09687; -6.73863 (El Arenosillo)

Equipment

Among the main facilities that INTA has at CEDEA are (updated 2009):

• Two automatic telemetry systems (fixed and mobile) in S and L bands
• HF, UHF and VHF communications systems
• Airborne and maritime surveillance radars, NORTHCONTROL
• Mobile path radar, VITRO RIR 778X, 250 Kw
• Radar path, TRACOR RIR 779C, 1 Mw
• 1Mw VITRO RIR 778C mobile path radar with destruction command
• Three autonomous mobile optronic stations, MSP 2000, equipped with IR, TV, cinema and radar sensors (3D, high precision and with telemetric capabilities)
• Weather center with real-time information, satellite data reception and complete radiosonde system
• Control center where all the information necessary for the supervision and monitoring of a launching operation (air traffic control, meteorology, cartography, sensor data integration, flight safety, etc.) is centralized.
• Evaluation center: preparation, analysis and evaluation of reports
• Two high speed cameras (10000 images/s)

Complementing the above, the Center also has:

• Meteorological laboratory and probe balloons
• Presentation and conference room
• Telemetry, radar and optronic workshops
• Mechanical workshop, electrical workshop, sanitary service and warehouses
• Accommodation service for operations
• Laboratory for photographic processing

In 2017 part of the equipment was damaged in a wildfire. In the years 2018 and 2019 INTA has dedicated part of its budget to replace damaged equipment.

• Sermiat – Unoperational. Used for Centaure rockets
• Médano del Loro – Operational. Is an adjacent launch site managed by Spanish Army

Launch history

The first launch of a rocket from El Arenosillo took place 15 October 1966.[4] Up to 1994 a total of 557 rockets were launched from this base, mainly of the Skua type for atmospheric soundings and in collaboration with other countries.[5]

All rockets for atmospheric soundings in Spain are launched from El Arenosillo.

In 2015 Delft Aerospace Rocket Engineering broke the European altitude record for amateur rocketry by launching the Stratos II+ rocket to 21.5 km altitude from El Arenosillo.[6]

On 1 March 2017, Zero 2 Infinity tested its first rocket, a Bloostar prototype, in El Arenosillo.[7] A balloon took Bloostar to 25 km. At 25 km the ignition of the rocket took place. The goals of the mission were: (i) validation of the telemetry systems in Space conditions, (ii) controlled ignition, (iii) stabilization of the rocket, (iv) monitoring of the launch sequence, (v) parachute deployment, and finally, (vi) sea recovery. All these goals were achieved in full.[8]

In 2022 PLD Space is expected to launch its first rocket Miura 1 from El Arenosillo.
