Arianespace launches CO3D constellation and MicroCarb satellite
Arianespace has completed the VV27 mission, successfully launching four CO3D satellites for Airbus Defence and Space alongside the French space agency CNESs MicroCarb satellite aboard a Vega C rocket from Europes Spaceport in French Guiana.
The CO3D constellation satellites were deployed into a 495 km Sun-synchronous orbit in pairs, 54 minutes after lift-off. MicroCarb, riding as an auxiliary payload, was placed in a higher orbit of 650 km, separating one hour and 41 minutes after launch.
David Cavaillolès, Arianespace CEO, said: 'VV27 is a great example of what our teams do best: delivering complex missions with precision. Vega C successfully placed five satellites into two different orbits, the four satellites composing the CO3D constellation and MicroCarb. This mission shows once again how Arianespace contributes to Europe's autonomous access to space and supports Airbus and the CNES in launching innovative missions furthering our understanding of the Earth.'
The CO3D (Constellation Optique 3D) satellites, built by Airbus in partnership with CNES, are designed to generate global high-resolution 3D digital surface models. Delivering 50 cm stereo and 2D imagery, these dual-use satellites support both military and civil applicationsfrom cartography and hydrology to urban planning and land management. Each 285 kg satellite operates on an all-electric platform and feeds data into a cloud-based ground segment developed by Airbus, with CNES providing the image processing system.
MicroCarb, developed by CNES, aims to map global carbon dioxide sources and sinks using a high-precision dispersive spectrometer. Built on the CNES Myriade platform, the mission will enhance understanding of CO? distribution in the atmosphere. The instrument was developed by Airbus Defence and Space, while Thales Alenia Space UK managed satellite integration under a partnership with the UK Space Agency.

Orange Suffers Cyberattack, Disrupts Operations in France
French telecommunications provider Orange has confirmed that it was targeted in a significant cyberattack on July 25, which breached one of its critical internal systems. The attack, which has caused considerable disruption to both business and consumer services, appears to be primarily focused on the company's operations in France. Orange's response to the incident has been swift, with the company prioritising efforts to contain the breach. According to initial reports, the attack compromised certain business operations, leading to service outages for some customers. While the full extent of the damage is still being assessed, Orange officials have indicated that they are working around the clock to restore all affected systems and services. The breach reportedly targeted Orange's internal infrastructure, including several business-critical systems that are vital for day-to-day operations. As a result, some business clients and consumers have faced service disruptions, including slower processing times and temporary unavailability of certain communication services. ADVERTISEMENT Orange's cybersecurity team, in collaboration with external experts, has initiated a full investigation into the breach to determine the scope of the attack and to identify the perpetrators. As part of its response, the company has implemented enhanced security protocols to prevent further intrusions while also focusing on mitigating any potential long-term impact on its operations and reputation. While Orange has not publicly named the threat actor responsible for the attack, cybersecurity experts believe the breach could be the work of an advanced persistent threat group. These groups are often highly sophisticated and well-funded, making them capable of executing complex cyberattacks that target large corporations and government entities. This cyberattack follows a growing trend of increasing threats faced by telecommunications companies, which are often seen as high-value targets due to the critical infrastructure they provide. With millions of customers relying on their services for both personal and business needs, any disruption in these services can have a profound impact on the affected parties. Orange has assured customers that it is taking every necessary step to restore normal service levels as soon as possible. However, given the scale and nature of the attack, it could take days or even weeks for full recovery depending on the extent of the systems affected. Business clients, in particular, have been urged to implement alternative communication and IT measures while the company works to bring services back online. The company also revealed that it has informed relevant data protection authorities and regulatory bodies of the breach, in accordance with EU regulations. The breach is expected to come under scrutiny from cybersecurity watchdogs, as well as from European data privacy regulators who are likely to investigate the incident to determine whether Orange has adhered to GDPR protocols. This event has raised concerns about the resilience of telecom companies' cybersecurity measures, particularly in the face of increasingly sophisticated cyber threats. The telecom sector, in particular, has become a frequent target for cybercriminals due to the vast amounts of sensitive data it handles, from customer personal details to confidential business communications. The scale of the attack has sent shockwaves through the broader tech and telecommunications industries, prompting other firms to reassess their own cybersecurity strategies. Analysts suggest that Orange's breach serves as a wake-up call for the sector, underscoring the need for telecom providers to invest heavily in robust security frameworks to defend against such threats.

Airlines in Middle East to test GPS alternatives as 'jamming' risk hits navigation
Airlines and governments in the Middle East have been invited to take part in the ongoing testing of a new navigation technology that some experts say is significantly more reliable than Global Positioning Satellite systems. SandboxAQ, a developer of products involving quantum technology and artificial intelligence, recently heralded the 'commercially available prototype' of the technology they're calling AQNav. This comes as GPS, the standard navigation system around the world, has become a victim of its own success, and is increasingly vulnerable to GPS jamming which can renders the navigation assistance unusable. GPS jamming − also known as GPS spoofing − became a prominent problem in June during the air war between Israel and Iran. Smartphone users across the Middle East reported anomalies with their GPS locations, which were wildly inaccurate. GPS has gained immense popularity thanks to the ease it can be incorporated into technology. But this ubiquity is becoming a growing vulnerability. SandboxAQ recently announced that Acubed, an Airbus company, completed what they're describing as 'rigorous real-world testing' of the touted GPS alternative, AQNav, which uses the magnetic field of the Earth along with quantum sensors that pick up the magnetic signals with the help of special AI software. Tests lasted five months and involved more than 100 flights that took place across 'diverse geographies and conditions'. According to SandboxAQ and Acubed, the test results show that AQNav 'consistently beat' the US Federal Aviation Administration's en route navigation standards. 'Pilots need to be able to trust their navigation systems,' Luca Ferrara, general manager for SandboxAQ's navigation business unit, told The National. 'When they can trust it, they're less stressed, they have less of a cognitive workload and they don't have worry about dealing with GPS loss,' he explained. SandboxAQ says that AQNav is rooted in and inspired by nature, and utilises the Earth's magnetic field, similar to how birds and other animals use it to navigate. That approach, combined with Sandbox AQ's proprietary AI software and use of hardware, gives it significantly more resilience and reliability compared to GPS, Mr Ferrara said. SandboxAQ also points out that unlike GPS, it doesn't connect to the internet, cloud or satellites. In the recent tests from Acubed, AQNav logged more than 44,000km, 'surpassing the Earth's circumference, without relying on GPS'. Mr Ferrara said more testing will now take place with hopes of eventually readying the system to be used on commercial airlines. SandboxAQ hopes to gain more insight into how to best position the magnetic censors used by the system on various aircraft, along with other details. Testing will help establish whether users would transfer navigation data to an existing computer on the plane, or a separate computer not connected to the internet or any network on board. This system is known as air-gapping, which is broadly viewed as more secure. 'Do we want it to pipe the data into the flight management computer or do we want it to go in an air-gapped way?' asked Mr Ferrara. He said Sandbox AQ currently has contracts with the US Air Force, and he expects the new navigation technology to first be adopted by defence and national security agencies, and then commercial entities. Through more testing, followed by a 'constructive dialogue' with aviation regulators around the world, Mr Ferrara said there's hope that commercial airlines will also be able to implement the system. Given the Middle East's increasingly strong presence in commercial aviation, with countries like the UAE playing a crucial role with international travel, it makes sense to push for testing among the region's airlines. 'We're looking for forward-leaning partners in the aerospace sector within the Gulf region to collaborate with,' Mr Ferrara said. He said the company is in discussions with several companies, and hopes to continue with those efforts given the Middle East's tourism footprint and globally recognised airline brands.
