<p dir="ltr">Boa tarde Colega Jorge,</p>
<p dir="ltr">Na especificação PHG, e por uma simplicidade, entenda-se menor número de bytes nas frames AX.25.,<br>
o formato foi "codificado" em digitos que correspondem aos valores em questão.<br>
Esta especificação refere AGL (Above Ground Level) ao invés de ASL (Above Sea Level)<br>
ver imagem anexa.<br>
No caso do APRS, entenda-se que esta é uma especificação do formato. Noutros sistemas, nomeadamente digitais, esse calculo poderá ser feito de outra forma.<br></p>

<p><font face="Arial">Não sendo um assunto que não domino entendo
que talvez esteja correto, nos sistemas digitais que controlo a
altura da antena é somada à altitude das coordenadas do local.
Se a antena estiver colocada numa torre de 12 mts e as
coordenadas do local indicarem que está 650 ASL o que aparece no
APRS é antenna: 662 mts. Isto no que eu conheço, mas é uma
questão que talvez o Mourato possa confirmar no caso do CQ0PLA.<br>
