That's a great question! The short answer is we don't know. Because the ignition process is basically the same as an old-school arc transmitter in the radio world, we can guess that during the actual pyro firing there's a burst of radio noise across a broad frequency range. I'd be surprised if that causes any "harm" to an Altus Metrum product nearby, and if you're doing the usual things like twisting leads to switches and match terminals, I wouldn't expect the induced noise to cause any unexpected pyro events, etc. But there's just no substitute for actual ground testing! I see that Apogee sells these, so perhaps give them a call and ask what they think they know about the product? https://www.apogeerockets.com/Electronics-Payloads/Altimeters/Lightning-Bug-Dual-Deployment-Altimeter Bdale
