# `Sidereon.Estimation.ScalarKalmanGains`
[🔗](https://github.com/neilberkman/sidereon-ex/blob/main/lib/sidereon/estimation.ex#L49)

Steady-state gains for a scalar constant-velocity Kalman filter.

`:position_gain` is the measurement gain on the level state. `:rate_gain` has
inverse-time units and satisfies `rate_gain * dt == beta` for the equivalent
alpha-beta filter.

# `t`

```elixir
@type t() :: %Sidereon.Estimation.ScalarKalmanGains{
  position_gain: float(),
  rate_gain: float()
}
```
