Azora's portable optical receiver latched onto Orion's signal from 240,000 miles

At 2:50am, as Orion came out from behind the Moon, the receiver in the parking lot locked onto its signal ^[4]. The capsule was about 11 times farther away than the geostationary satellite in the receiver's only earlier successful test ^[1].

The pitch is cost-effective optical communication between space and Earth ^[3], and Azora says the lock proves its system can support an optical link at 240,000 miles ^[5]. That night, a new receiver found a signal at lunar distance and locked onto it ^[4]. The published account of the test does not include a data rate for the link or a price for the receiver.

A ground-station team needs those two figures before it can defend a pilot budget. Honeywell supplies one of them for its own product. It says its Transportable Optical Ground Station, a shipping container with a retractable telescope, provides a 1Gbps link to low Earth orbit satellites ^[13]. Honeywell's figure is a data rate to low orbit, while Azora's headline figure is a distance to the Moon. The Honeywell station also supports the BB84 quantum key distribution standard ^[14], and UK startup Archangel Lightworks has built a station that is a lot smaller ^[15].

Azora's work is aimed at cost and deployability ^[17]. Optical signals can still be disrupted by adverse weather ^[8].

Azora's CTO describes a military buyer. "RF denial is a big problem," said Martin Lavery, who is also professor of optics at the University of Glasgow ^{[10] [12]}. "It's likely any future conflicts will involve some form of RF denial, because that in turn hits GPS, and our communication with satellites and other units," he said ^[16]. Of a laser link, he said, "The only way to stop it is to stand right in the middle of the beam" ^[11]. He is describing a product category his own company sells ^[12].

For a team making the choice, the case sorts on two axes. The first is whether radio is the bottleneck, either on volume or because someone can jam it. The second is whether the operation can wait out a cloudy night. If radio is not the bottleneck, stay on RF, whatever distance the demo reached. If it is and the operation can wait, a portable optical terminal is a reasonable pilot, priced against Honeywell's container once Azora states a sustained data rate. If it is and the operation cannot wait, the plan needs more than one site or an RF fallback, and portability should be judged by how quickly a terminal can be moved.

I'd put Azora in the pilot box. The tradeoff is early access to hardware with one deep-space result behind it, set against waiting for the throughput number that would let anyone compare it with the alternatives.
