论文摘要
该技术公报旨在在同一作者的早期论文中纠正错误的陈述（引理2.4），该论文涉及对线性时变（LTV）系统的足够可观察性的足够条件。在此之前的论文中，另外两个引理的证据，关于范围测量值的身体置估，取决于此错误的陈述。为了简洁起见，仅提出了这些引理之一的新证明，第二张引理的证明是它的简单版本。
This technical communiqué aims at correcting an erroneous statement (Lemma 2.4) in an earlier paper by the same authors concerning a sufficient condition of uniform observability for a Linear Time-Varying (LTV) system. In this earlier paper, the proofs of two other lemmas, about body-pose estimation from range measurements, relied on this erroneous statement. For the sake of conciseness, only a new proof of one of these lemmas is presented, the proof of the second lemma being a simpler version of it.
