How K2 solved the tens-of-millions-of-points problem

Manufacturing next-gen satellite constellations produces nearly 20 million data points per second. See how K2 streams it live to never miss the mark.

Real Customer Achievements

Sift [is] critical in making operations seamless, automatically flagging out-of-bounds telemetry, and helping us close the design loop by using real-world data to improve.

Core Capabilities

Catch anomalies the moment they happen and protect safety-critical hardware

K2's engineers watch live telemetry on the test stand and act on anomalies the instant they appear. Using Sift, they see out-of-bounds readings as data streams in, with write latency under one second even as the hardware produces nearly 20 million data points per second. That visibility means a single missed threshold no longer risks destroying a costly asset or putting the team at risk during a critical test.

Scale testing across the entire production line without adding engineering hours.

K2 separates signal from noise across its entire production line, not just one test stand, with Sift parsing terabytes of telemetry per test day. On Sift, the team works through high cardinality, constantly changing schemas, and both live and historical data without forced migrations or crashes. As a result, K2 can push toward constellations carrying millions of sensors while keeping its engineering team lean.

Shorten the time from data to decision with shared context.

which configuration, what changed since the last run. With Sift's shareable links, they drop the screenshots, one-off Python scripts, and scattered web servers, and the view holds during launch when hundreds open the same link at once. K2 closes the design loop with real data, on one timeline from test to ops.

Let’s talk about how Sift can streamline development, reduce risk, and accelerate certification.
