<p dir="ltr">Na especificação PHG, e por uma simplicidade, entenda-se menor número de bytes nas frames AX.25.,<br>
o formato foi &quot;codificado&quot; 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>
